http_get_dos is a very basic HTTP tool, written to find the maximum throughput a computer can physically produce, in terms of requests per second.
Everything runs in one thread, for maximum performance. Only plain HTTP is supported.
$ http_get_dos --help
Usage: http_get_dos [OPTIONS...] URL
OPTIONS
-n, --requests=N Total number of requests
-c, --concurrency=N Number of concurrent connections

-h, --help Display this help and exit
Send 1M requests to your localhost web server, adding a custom header:
$ http_get_dos -n 1000000 -c 1000 -H "Connection: keep-alive" http://localhost/path
