httpress

High performance HTTP server stress & benchmark utility.

Inspired by weighttp tool.

Originally written by yarosla at Bitbucket and modified by Parallels Performance Team.

Main features:

• event driven (low memory footprint, large number of connections)
• multi-threaded (uses all cores of your CPU)
• SSL support (via GNUTLS library) with cipher suite selection

Compared to weighttp, httpress offers the following improvements:

• evenly distributes load between threads; does not allow one thread to finish much earlier than others
• promptly timeouts stucked connections, forces all hanging connections to close after the main run, does not allow hanging or interrupted connections to affect the measurement
• SSL support

Usage

httpress <options> <url>
  -n num   number of requests     (default: 1)
  -t num   number of threads      (default: 1)
  -c num   concurrent connections (default: 1)
  -k       keep alive             (default: no)
  -z pri   GNUTLS cipher priority (default: NORMAL)
  -h       show this help

example: httpress -n 10000 -c 100 -t 4 -k http://localhost:8080/index.html

Dependencies

• Depends on libev library
• Depends on http-parser library
• Depends on LibParserUtils library
• Depends on uchardet library
• Depends on GnuTLS library (if compiled with SSL support)

Building from source

1. Prerequisite (your distro might have these in repo; otherwise build from source):
2. libev 4 library
3. http-parser 2 library
4. LibParserUtils 0.2.0 library
5. uchardet library
6. SSL prerequisite: GnuTLS 3.0 library (better build from source)
7. Download httpress source
8. Run make or make -f Makefile.nossl
9. Collect executable from bin subdirectory
