This aims at further reducing the contention on the free_list when using global pools. The free_list pointer now appears for each bucket, and both the alloc and the release code skip to a next bucket when ending on a contended entry. The default entry used for allocations and releases depend on the thread ID so that locality is preserved as much as possible under low contention. It would be nice to improve the situation to make sure that releases to the shared pools doesn't consider the first entry's pointer but only an argument that would be passed and that would correspond to the bucket in the thread's cache. This would reduce computations and make sure that the shared cache only contains items whose pointers match the same bucket. This was not yet done. One possibility could be to keep the same splitting in the local cache. With this change, an h2load test with 5 * 160 conns & 40 streams on 80 threads that was limited to 368k RPS with the shared cache jumped to 3.5M RPS for 8 buckets, 4M RPS for 16 buckets, 4.7M RPS for 32 buckets and 5.5M RPS for 64 buckets. |

The HAProxy documentation has been split into a number of different files for ease of use. 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)
