The new "bytime" sorting criterion uses the reported CPU time instead of the usage. This is convenient to spot tasks that are mostly reponsible for the CPU usage in a running process. It supports both the detailed and the aggregated format. The output looks like this: > show profiling tasks bytime Tasks activity: function calls cpu_tot cpu_avg lat_tot lat_avg qc_io_cb 117739 1.961m 999.1us 37.45s 318.1us <- h3_snd_buf@src/h3.c:1084

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)
