Threads have long matured by now, still for most users their usage is not trivial. It's about time to enable them by default on platforms where we know the number of CPUs bound. This patch does this, it counts the number of CPUs the process is bound to upon startup, and enables as many threads by default. Of course, "nbthread" still overrides this, but if it's not set the default behaviour is to start one thread per CPU. The default number of threads is reported in "haproxy -vv". Simply using "taskset -c" is now enough to adjust this number of threads so that there is no more need for playing with cpu-map. And thanks to the previous patches on the listener, the vast majority of configurations will not need to duplicate "bind" lines with the "process x/y" statement anymore either, so a simple config will automatically adapt to the number of processors available.
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 - 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)
