|
|
|
||
|
|
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
|
||
|
|
|
||
|
|
```sh
|
||
|
|
make # build optimized binary
|
||
|
|
make debug # build with debug symbols
|
||
|
|
make valgrind # run memory leak tests
|
||
|
|
make clean # remove build artifacts
|
||
|
|
```
|
||
|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
```sh
|
||
|
|
./abr -n <requests> -c <concurrency> [-k] [-i] <url>
|
||
|
|
```
|
||
|
|
|
||
|
|
## Python Version
|
||
|
|
|
||
|
|
Uses asyncio with aiohttp for concurrent HTTP requests.
|
||
|
|
|
||
|
|
### Requirements
|
||
|
|
|
||
|
|
- Python 3.7+
|
||

|
||
|
|
|
||
|
|
### Install
|
||
|
|
|

|
|
|
||
|
|
### Usage
|
||
|
|
|
||
|
|
```sh
|
||
|
|
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
|
||
|
|
|
||
|
|
```sh
|
||
|
|
./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)
|
||
|
