Cpufreq alone isn't a good metric on heterogenous CPUs because efficient cores can reach almost as high frequencies as performant ones. Tests have shown that majoring performance cores by 50% gives a pretty accurate estimate of the performance to expect on modern CPUs, and that counting +33% per extra SMT thread is reasonable as well. We don't have the info about the core's quality, but using the presence of SMT is a reasonable approach in this case, given that efficiency cores will not use it. As an example, using one thread of each of the 8 P-cores of an intel i9-14900k gives 395k rps for a corrected total capacity of 69.3k, using the 16 E-cores gives 40.5k for a total capacity of 70.4k, and using both threads of 6 P-cores gives 41.1k for a total capacity of 69.6k. Thus the 3 same scores deliver the same performance in various combinations.
HAProxy
HAProxy is a free, very fast and reliable reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications.
Installation
The INSTALL file describes how to build HAProxy. A list of packages is also available on the wiki.
Getting help
The discourse and the mailing-list are available for questions or configuration assistance. You can also use the slack or IRC channel. Please don't use the issue tracker for these.
The issue tracker is only for bug reports or feature requests.
Documentation
The HAProxy documentation has been split into a number of different files for ease of use. It is available in text format as well as HTML. The wiki is also meant to replace the old architecture guide.
Please refer to the following files depending on what you're looking for:
- INSTALL for instructions on how to build and install HAProxy
- BRANCHES to understand the project's life cycle and what version to use
- LICENSE for the project's license
- CONTRIBUTING for the process to follow to submit contributions
The more detailed documentation is located into the doc/ directory:
- doc/intro.txt for a quick introduction on HAProxy
- doc/configuration.txt for the configuration's reference manual
- doc/lua.txt for the Lua's reference manual
- doc/SPOE.txt for how to use the SPOE engine
- doc/network-namespaces.txt for how to use network namespaces under Linux
- doc/management.txt for the management guide
- doc/regression-testing.txt for how to use the regression testing suite
- doc/peers.txt for the peers protocol reference
- doc/coding-style.txt for how to adopt HAProxy's coding style
- doc/internals for developer-specific documentation (not all up to date)
