## [2025-04-17] Implemented High Volume Stress Testing Solution for SDK
|
||||
|
||||
**Feature:** Comprehensive stress testing framework using `arun_many` and the dispatcher system to evaluate performance, concurrency handling, and identify potential issues under high-volume crawling scenarios.
|
||||
|
||||
**Changes Made:**
|
||||
1. Created a dedicated stress testing framework in the `benchmarking/` (or similar) directory.
|
||||
2. Implemented local test site generation (`SiteGenerator`) with configurable heavy HTML pages.
|
||||
3. Added basic memory usage tracking (`SimpleMemoryTracker`) using platform-specific commands (avoiding `psutil` dependency for this specific test).
|
||||
4. Utilized `CrawlerMonitor` from `crawl4ai` for rich terminal UI and real-time monitoring of test progress and dispatcher activity.
|
||||
5. Implemented detailed result summary saving (JSON) and memory sample logging (CSV).
|
||||
6. Developed `run_benchmark.py` to orchestrate tests with predefined configurations.
|
||||
7. Created `run_all.sh` as a simple wrapper for `run_benchmark.py`.
|
||||
|
||||
**Implementation Details:**
|
||||
- Generates a local test site with configurable pages containing heavy text and image content.
|
||||
- Uses Python's built-in `http.server` for local serving, minimizing network variance.
|
||||
- Leverages `crawl4ai`'s `arun_many` method for processing URLs.
|
||||
- Utilizes `MemoryAdaptiveDispatcher` to manage concurrency via the `max_sessions` parameter (note: memory adaptation features require `psutil`, not used by `SimpleMemoryTracker`).
|
||||
- Tracks memory usage via `SimpleMemoryTracker`, recording samples throughout test execution to a CSV file.
|
||||
- Uses `CrawlerMonitor` (which uses the `rich` library) for clear terminal visualization and progress reporting directly from the dispatcher.
|
||||
- Stores detailed final metrics in a JSON summary file.
|
||||
|
||||
**Files Created/Updated:**
|
||||
- `stress_test_sdk.py`: Main stress testing implementation using `arun_many`.
|
||||
- `benchmark_report.py`: (Assumed) Report generator for comparing test results.
|
||||
- `run_benchmark.py`: Test runner script with predefined configurations.
|
||||
- `run_all.sh`: Simple bash script wrapper for `run_benchmark.py`.
|
||||
- `USAGE.md`: Comprehensive documentation on usage and interpretation (updated).
|
||||
|
||||
**Testing Approach:**
|
||||
- Creates a controlled, reproducible test environment with a local HTTP server.
|
||||
- Processes URLs using `arun_many`, allowing the dispatcher to manage concurrency up to `max_sessions`.
|
||||
- Optionally logs per-batch summaries (when not in streaming mode) after processing chunks.
|
||||
- Supports different test sizes via `run_benchmark.py` configurations.
|
||||
- Records memory samples via platform commands for basic trend analysis.
|
||||
- Includes cleanup functionality for the test environment.
|
||||
|
||||
**Challenges:**
|
||||
- Ensuring proper cleanup of HTTP server processes.
|
||||
- Getting reliable memory tracking across platforms without adding heavy dependencies (`psutil`) to this specific test script.
|
||||
- Designing `run_benchmark.py` to correctly pass arguments to `stress_test_sdk.py`.
|
||||
|
||||
**Why This Feature:**
|
||||
The high volume stress testing solution addresses critical needs for ensuring Crawl4AI's `arun_many` reliability:
|
||||
1. Provides a reproducible way to evaluate performance under concurrent load.
|
||||
2. Allows testing the dispatcher's concurrency control (`max_session_permit`) and queue management.
|
||||
3. Enables performance tuning by observing throughput (`URLs/sec`) under different `max_sessions` settings.
|
||||
4. Creates a controlled environment for testing `arun_many` behavior.
|
||||
5. Supports continuous integration by providing deterministic test conditions for `arun_many`.
|
||||
|
||||
**Design Decisions:**
|
||||
- Chose local site generation for reproducibility and isolation from network issues.
|
||||
- Utilized the built-in `CrawlerMonitor` for real-time feedback, leveraging its `rich` integration.
|
||||
- Implemented optional per-batch logging in `stress_test_sdk.py` (when not streaming) to provide chunk-level summaries alongside the continuous monitor.
|
||||
- Adopted `arun_many` with a `MemoryAdaptiveDispatcher` as the core mechanism for parallel execution, reflecting the intended SDK usage.
|
||||
- Created `run_benchmark.py` to simplify running standard test configurations.
|
||||
- Used `SimpleMemoryTracker` to provide basic memory insights without requiring `psutil` for this particular test runner.
|
||||
|
||||
**Future Enhancements to Consider:**
|
||||
- Create a separate test variant that *does* use `psutil` to specifically stress the memory-adaptive features of the dispatcher.
|
||||
- Add support for generated JavaScript content.
|
||||
- Add support for Docker-based testing with explicit memory limits.
|
||||
- Enhance `benchmark_report.py` to provide more sophisticated analysis of performance and memory trends from the generated JSON/CSV files.

## [2025-04-17] Refined Stress Testing System Parameters and Execution
|
||||
|
||||
**Changes Made:**
|
||||
1. Corrected `run_benchmark.py` and `stress_test_sdk.py` to use `--max-sessions` instead of the incorrect `--workers` parameter, accurately reflecting dispatcher configuration.
|
||||
2. Updated `run_benchmark.py` argument handling to correctly pass all relevant custom parameters (including `--stream`, `--monitor-mode`, etc.) to `stress_test_sdk.py`.
|
||||
3. (Assuming changes in `benchmark_report.py`) Applied dark theme to benchmark reports for better readability.
|
||||
4. (Assuming changes in `benchmark_report.py`) Improved visualization code to eliminate matplotlib warnings.
|
||||
5. Updated `run_benchmark.py` to provide clickable `file://` links to generated reports in the terminal output.
|
||||
6. Updated `USAGE.md` with comprehensive parameter descriptions reflecting the final script arguments.
|
||||
7. Updated `run_all.sh` wrapper to correctly invoke `run_benchmark.py` with flexible arguments.
|
||||
|
||||
**Details of Changes:**
|
||||
|
||||
1. **Parameter Correction (`--max-sessions`)**:
|
||||
* Identified the fundamental misunderstanding where `--workers` was used incorrectly.
|
||||
* Refactored `stress_test_sdk.py` to accept `--max-sessions` and configure the `MemoryAdaptiveDispatcher`'s `max_session_permit` accordingly.
|
||||
* Updated `run_benchmark.py` argument parsing and command construction to use `--max-sessions`.
|
||||
* Updated `TEST_CONFIGS` in `run_benchmark.py` to use `max_sessions`.
|
||||
|
||||
2. **Argument Handling (`run_benchmark.py`)**:
|
||||
* Improved logic to collect all command-line arguments provided to `run_benchmark.py`.
|
||||
* Ensured all relevant arguments (like `--stream`, `--monitor-mode`, `--port`, `--use-rate-limiter`, etc.) are correctly forwarded when calling `stress_test_sdk.py` as a subprocess.
|
||||
|
||||
3. **Dark Theme & Visualization Fixes (Assumed in `benchmark_report.py`)**:
|
||||
* (Describes changes assumed to be made in the separate reporting script).
|
||||
|
||||
4. **Clickable Links (`run_benchmark.py`)**:
|
||||
* Added logic to find the latest HTML report and PNG chart in the `benchmark_reports` directory after `benchmark_report.py` runs.
|
||||
* Used `pathlib` to generate correct `file://` URLs for terminal output.
|
||||
|
||||
5. **Documentation Improvements (`USAGE.md`)**:
|
||||
* Rewrote sections to explain `arun_many`, dispatchers, and `--max-sessions`.
|
||||
* Updated parameter tables for all scripts (`stress_test_sdk.py`, `run_benchmark.py`).
|
||||
* Clarified the difference between batch and streaming modes and their effect on logging.
|
||||
* Updated examples to use correct arguments.
|
||||
|
||||
**Files Modified:**
|
||||
- `stress_test_sdk.py`: Changed `--workers` to `--max-sessions`, added new arguments, used `arun_many`.
|
||||
- `run_benchmark.py`: Changed argument handling, updated configs, calls `stress_test_sdk.py`.
|
||||
- `run_all.sh`: Updated to call `run_benchmark.py` correctly.
|
||||
- `USAGE.md`: Updated documentation extensively.
|
||||
- `benchmark_report.py`: (Assumed modifications for dark theme and viz fixes).
|
||||
|
||||
**Testing:**
|
||||
- Verified that `--max-sessions` correctly limits concurrency via the `CrawlerMonitor` output.
|
||||
- Confirmed that custom arguments passed to `run_benchmark.py` are forwarded to `stress_test_sdk.py`.
|
||||
- Validated clickable links work in supporting terminals.
|
||||
- Ensured documentation matches the final script parameters and behavior.
|
||||
|
||||
**Why These Changes:**

# Crawl4AI Stress Testing and Benchmarking
|
||||
|
||||
This directory contains tools for stress testing Crawl4AI's `arun_many` method and dispatcher system with high volumes of URLs to evaluate performance, concurrency handling, and potentially detect memory issues. It also includes a benchmarking system to track performance over time.
|
||||
|
||||
## Quick Start
|
||||
|
||||
```bash
|
||||
# Run a default stress test (small config) and generate a report
|
||||
# (Assumes run_all.sh is updated to call run_benchmark.py)
|
||||
./run_all.sh
|
||||
```
|
||||
*Note: `run_all.sh` might need to be updated if it directly called the old script.*
|
||||
|
||||
## Overview
|
||||
|
||||
The stress testing system works by:
|
||||
|
||||
1. Generating a local test site with heavy HTML pages (regenerated by default for each test).
|
||||
2. Starting a local HTTP server to serve these pages.
|
||||
3. Running Crawl4AI's `arun_many` method against this local site using the `MemoryAdaptiveDispatcher` with configurable concurrency (`max_sessions`).
|
||||
4. Monitoring performance metrics via the `CrawlerMonitor` and optionally logging memory usage.
|
||||
5. Optionally generating detailed benchmark reports with visualizations using `benchmark_report.py`.
|
||||
|
||||
## Available Tools
|
||||
|
||||
- `test_stress_sdk.py` - Main stress testing script utilizing `arun_many` and dispatchers.
|
||||
- `benchmark_report.py` - Report generator for comparing test results (assumes compatibility with `test_stress_sdk.py` outputs).
|
||||
- `run_benchmark.py` - Python script with predefined test configurations that orchestrates tests using `test_stress_sdk.py`.
|
||||
- `run_all.sh` - Simple wrapper script (may need updating).
|
||||
|
||||
## Usage Guide
|
||||
|
||||
### Using Predefined Configurations (Recommended)
|
||||
|
||||
The `run_benchmark.py` script offers the easiest way to run standardized tests:
|
||||
|
||||
```bash
|
||||
# Quick test (50 URLs, 4 max sessions)
|
||||
python run_benchmark.py quick
|
||||
|
||||
# Medium test (500 URLs, 16 max sessions)
|
||||
python run_benchmark.py medium
|
||||
|
||||
# Large test (1000 URLs, 32 max sessions)
|
||||
python run_benchmark.py large
|
||||
|
||||
# Extreme test (2000 URLs, 64 max sessions)
|
||||
python run_benchmark.py extreme
|
||||
|
||||
# Custom configuration
|
||||
python run_benchmark.py custom --urls 300 --max-sessions 24 --chunk-size 50
|
||||
|
||||
# Run 'small' test in streaming mode
|
||||
python run_benchmark.py small --stream
|
||||
|
||||
# Override max_sessions for the 'medium' config
|
||||
python run_benchmark.py medium --max-sessions 20
|
||||
|
||||
# Skip benchmark report generation after the test
|
||||
python run_benchmark.py small --no-report
|
||||
|
||||
# Clean up reports and site files before running

|
||||
|
||||
```bash
|
||||
# Generate a report from existing test results in ./reports/
|
||||
python benchmark_report.py
|
||||
|

|
||||
|
||||
## Understanding the Test Output
|
||||
|
||||
### Real-time Progress Display (`CrawlerMonitor`)
|
||||
|
||||
When running `test_stress_sdk.py`, the `CrawlerMonitor` provides a live view of the crawling process managed by the dispatcher.
|
||||
|
||||
- **DETAILED Mode (Default):** Shows individual task status (Queued, Active, Completed, Failed), timings, memory usage per task (if `psutil` is available), overall queue statistics, and memory pressure status (if `psutil` available).
|
||||
- **AGGREGATED Mode:** Shows summary counts (Queued, Active, Completed, Failed), overall progress percentage, estimated time remaining, average URLs/sec, and memory pressure status.
|
||||
|
||||
### Batch Log Output (Non-Streaming Mode Only)
|
||||
|
||||
If running `test_stress_sdk.py` **without** the `--stream` flag, you will *also* see per-batch summary lines printed to the console *after* the monitor display, once each chunk of URLs finishes processing:
|
||||
|
||||
```
|
||||
Batch | Progress | Start Mem | End Mem | URLs/sec | Success/Fail | Time (s) | Status
|
||||
───────────────────────────────────────────────────────────────────────────────────────────

This display provides chunk-specific metrics:
|
||||
- **Batch**: The batch number being reported.
|
||||
- **Progress**: Overall percentage of total URLs processed *after* this batch.
|
||||
- **Start Mem / End Mem**: Memory usage before and after processing this batch (if tracked).
|
||||
- **URLs/sec**: Processing speed *for this specific batch*.
|
||||
- **Success/Fail**: Number of successful and failed URLs *in this batch*.
|
||||
- **Time (s)**: Wall-clock time taken to process *this batch*.
|
||||
- **Status**: Color-coded status for the batch outcome.
|
||||
|
||||
### Summary Output
|
||||

|
||||
```
|
||||
|
||||
### HTML Report Structure (Generated by `benchmark_report.py`)
|
||||
|
||||
(This section remains the same, assuming `benchmark_report.py` generates these)
|
||||
The benchmark report contains several sections:
|
||||
1. **Summary**: Overview of the latest test results and trends
|
||||
2. **Performance Comparison**: Charts showing throughput across tests
|
||||
3. **Memory Usage**: Detailed memory usage graphs for each test
|
||||
4. **Detailed Results**: Tabular data of all test metrics
|
||||
5. **Conclusion**: Automated analysis of performance and memory patterns
|
||||
|
||||
### Memory Metrics
|
||||
|
||||
(This section remains conceptually the same)
|
||||
Memory growth is the key metric for detecting leaks...
|
||||
|
||||
### Performance Metrics
|
||||
|
||||
(This section remains conceptually the same, though "URLs per Worker" is less relevant - focus on overall URLs/sec)
|
||||
Key performance indicators include:
|
||||
- **URLs per Second**: Higher is better (throughput)
|
||||
- **Success Rate**: Should be 100% in normal conditions
|
||||
- **Total Processing Time**: Lower is better
|
||||
- **Dispatcher Efficiency**: Observe queue lengths and wait times in the monitor (Detailed mode)
|
||||
|
||||
### Raw Data Files
|
||||
|
||||
Raw data is saved in the `--report-path` directory (default `./reports/`):
|
||||
|
||||
- **JSON files** (`test_summary_*.json`): Contains the final summary for each test run.
|
||||
- **CSV files** (`memory_samples_*.csv`): Contains time-series memory samples taken during the test run.
|
||||
|
||||
Example of reading raw data:
|
||||
```python
|
||||
import json
|
||||
import pandas as pd
|
||||
|
||||
# Load test summary
|
||||
test_id = "20250418_103015" # Example ID
|
||||
with open(f'reports/test_summary_{test_id}.json', 'r') as f:
|
||||
results = json.load(f)
|
||||
|
||||
# Load memory samples
|
||||
memory_df = pd.read_csv(f'reports/memory_samples_{test_id}.csv')
|
||||
|
||||
# Analyze memory_df (e.g., calculate growth, plot)
|
||||
if not memory_df['memory_info_mb'].isnull().all():
|
||||
growth = memory_df['memory_info_mb'].iloc[-1] - memory_df['memory_info_mb'].iloc[0]
|
||||
print(f"Total Memory Growth: {growth:.1f} MB")
|
||||
else:
|
||||
print("No valid memory samples found.")
|
||||
|
||||
print(f"Avg URLs/sec: {results['urls_processed'] / results['total_time_seconds']:.2f}")
|
||||
```
|
||||
|
||||
## Visualization Dependencies
|
||||
|
||||
(This section remains the same)
|
||||
For full visualization capabilities in the HTML reports generated by `benchmark_report.py`, install additional dependencies...
|
||||
|
||||
## Directory Structure
|
||||
|
||||
```
|
||||
benchmarking/ # Or your top-level directory name
|
||||
├── benchmark_reports/ # Generated HTML reports (by benchmark_report.py)
|
||||
├── reports/ # Raw test result data (from test_stress_sdk.py)
|
||||
├── test_site/ # Generated test content (temporary)
|
||||
├── benchmark_report.py# Report generator
|
||||
├── run_benchmark.py # Test runner with predefined configs
|
||||
├── test_stress_sdk.py # Main stress test implementation using arun_many
|
||||
└── run_all.sh # Simple wrapper script (may need updates)
|
||||
#└── requirements.txt # Optional: Visualization dependencies for benchmark_report.py
|
||||
```
|
||||
|
||||
## Cleanup
|
||||
|
||||
To clean up after testing:
|
||||
|
||||
```bash
|
||||
# Remove the test site content (if not using --keep-site)
|
||||
rm -rf test_site
|
||||
|
||||
# Remove all raw reports and generated benchmark reports
|
||||
rm -rf reports benchmark_reports
|
||||
|
||||
# Or use the --clean flag with run_benchmark.py
|
||||
python run_benchmark.py medium --clean
|
||||
```
|
||||
|
||||
## Use in CI/CD
|
||||
|
||||
(This section remains conceptually the same, just update script names)
|
||||
These tests can be integrated into CI/CD pipelines:
|
||||
```bash
|
||||
# Example CI script
|
||||
python run_benchmark.py medium --no-report # Run test without interactive report gen
|
||||
# Check exit code
|
||||
if [ $? -ne 0 ]; then echo "Stress test failed!"; exit 1; fi
|
||||
# Optionally, run report generator and check its output/metrics
|
||||
# python benchmark_report.py
|
||||
# check_report_metrics.py reports/test_summary_*.json || exit 1
|
||||
exit 0
|
||||
```
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
- **HTTP Server Port Conflict**: Use `--port` with `run_benchmark.py` or `test_stress_sdk.py`.
|
||||
- **Memory Tracking Issues**: The `SimpleMemoryTracker` uses platform commands (`ps`, `/proc`, `tasklist`). Ensure these are available and the script has permission. If it consistently fails, memory reporting will be limited.
|
||||
- **Visualization Missing**: Related to `benchmark_report.py` and its dependencies.
|
||||
- **Site Generation Issues**: Check permissions for creating `./test_site/`. Use `--skip-generation` if you want to manage the site manually.
|
||||
- **Testing Against External Site**: Ensure the external site is running and use `--use-existing-site --port <correct_port>`.
