Multi-threading
The multi-threading model is a feature that allows HAProxy Enterprise to start multiple threads within a single process. With the multi-threading model, you benefit from the following features:
Information is shared between threads, such as configuration parameters, statistics, limits, and rates
Less health checking traffic
Runtime API commands become simpler compared with running in multi-process mode (e.g.
nbproc
) because you do not need to issue commands against multiple processes or script loops
Configure multi-threading
To change the number of threads HAProxy Enterprise runs, set the option nbthread
in the global
configuration section. Optionally, map threads to CPU cores using the configuration directive cpu-map
.
global nbthread 4 # bind all threads of the first process on the first 4 CPUs cpu-map 1/all 0-3
