HAProxy - Load balancer
023564b685
The zero-copy forwarding or the mux-to-mux forwarding is a way to fast-forward data without using the channels buffers. Data are transferred from a mux to the other one. The kernel splicing is an optimization of the zero-copy forwarding. But it can also use normal buffers (but not channels ones). This way, it could be possible to fast-forward data with muxes not supporting the kernel splicing (H2 and H3 muxes) but also with applets. However, this mode can introduce regressions or bugs in future (just like the kernel splicing). Thus, It could be usefull to disable this optim. To do so, in configuration, the global tune settting 'tune.disable-zero-copy-forwarding' may be set in a global section or the '-dZ' command line parameter may be used to start HAProxy. Of course, this also disables the kernel splicing. |

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)
