We don't need to know very accurately how much RAM is needed in a pool, however we must not spend time competing with other threads trying to be the one with the most accurate value. Let's use the "_opportunistic" variants of swrate_add() which will simply cause some updates to be dropped in case of thread contention. This should significantly improve the situation when dealing with many threads and small per-thread caches. Performance gains of up to 1-2% were observed on 48-thread systems thanks to this alone.

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)
