HAProxy is free, open source software that provides a high availability load balancer and proxy server for TCP and HTTP-based applications that spreads requests across multiple servers.[2] It is written in C[3] and has a reputation for being fast and efficient (in terms of processor and memory usage).[4]

HAProxy is used by a number of high-profile websites including GitHub, Bitbucket,[5] Stack Overflow,[6] Reddit, Tumblr, Twitter[7][8] and Tuenti[9] and is used in the OpsWorks product from Amazon Web Services.[10]

History

HAProxy was written in 2000[11] by Willy Tarreau,[12] a core contributor to the Linux kernel[13] who still maintains the project.

Performance

Servers equipped with a dual-core Opteron or Xeon processor generally achieve between 15000 and 40000 hits per second, and have no trouble saturating a 2 Gbit/sec connection under Linux.[14]
