+        bool "SLUB per cpu partial cache"
+        help
+          Per cpu partial caches accellerate 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.
