Despite having replaced the SSL BIOs to use our own raw_sock layer, we still didn't exploit the CO_SFL_MSG_MORE flag which is pretty useful to avoid sending incomplete packets. It's particularly important for SSL since the extra overhead almost guarantees that each send() will be followed by an incomplete (and often odd-sided) segment. We already have an xprt_st set of flags to pass info to the various layers, so let's just add a new one, SSL_SOCK_SEND_MORE, that is set or cleared during ssl_sock_from_buf() to transfer the knowledge of CO_SFL_MSG_MORE. This way we can recover this information and pass it to raw_sock. This alone is sufficient to increase by ~5-10% the H2 bandwidth over SSL when multiple streams are used in parallel.
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)
