In linux kernel since version 4.14.326 (release Date: 2023-09-23)
Per cpu partial caches accelerate objects allocation and freeing
that is local to a processor at the price of more indeterminism
in the latency of the free. On overflow these caches will be cleared
which requires the taking of locks that may cause latency spikes.
Typically one would choose no for a realtime system.
