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 <requests> -c <concurrency> [-k] [-i] <url>
Python Version
Uses asyncio with aiohttp for concurrent HTTP requests.
Requirements
- Python 3.7+
- aiohttp
Install
make py-install
Usage
python3 abr.py -n <requests> -c <concurrency> [-k] [-i] <url>
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
C Version
