abr

HTTP benchmark tool inspired by ApacheBench. Available in C and Python implementations.

C Version

Uses non-blocking sockets with poll() multiplexing and OpenSSL for TLS.

Requirements

GCC
OpenSSL development libraries (libssl-dev)
POSIX-compliant system (Linux, BSD, macOS)

Build

make # build optimized binary
make debug # build with debug symbols
make valgrind # run memory leak tests
make clean # remove build artifacts

Usage

./abr -n  -c  [-k] [-i]

Python Version

Uses asyncio with aiohttp for concurrent HTTP requests.

Requirements

Python 3.7+
aiohttp

Install

make py-install

Usage

python3 abr.py -n  -c  [-k] [-i] 
make py-run # quick test run
make py-test # test with more requests

Options

| Option | Description | |--------|-------------| | -n | Total number of requests | | -c | Concurrent connections (max 10000) | | -k | Enable HTTP Keep-Alive | | -i | Skip SSL certificate verification |

Example

./abr -n 1000 -c 50 -k https://example.com/
python3 abr.py -n 1000 -c 50 -k https://example.com/

Output

Requests per second
Transfer rate (KB/s)
Response time percentiles (50th, 66th, 75th, 80th, 90th, 95th, 98th, 99th)
Connection time statistics (min, mean, median, max, standard deviation)

Technical Details

Graceful shutdown on SIGINT/SIGTERM
OpenSSL 1.0.x and 1.1+ compatibility
Memory leak free (verified with valgrind)

Python Version

Async I/O with asyncio and aiohttp
Connection pooling with keep-alive support
30-second per-request timeout
Graceful shutdown on SIGINT/SIGTERM
