NativePoolMaxThreads Directive

NativePoolMaxThreads determine the maximum number of threads in the native (kernel) thread pool.

A higher value allows more requests to execute concurrently, but has more overhead due to context switching, so bigger is not always better. Typically, you do not need to increase this number, but if the CPU is not saturated and you see requests queue up, then increase this number.


You can modify the NativePoolMaxThreads by editing the NativePoolMaxThreads parameter in magnus.conf.
