Also see: kernel.org
Each cache maintains blocks of contiguous pages in memory called slabs
$ sudo slabtop
You can sort the real time information by using these options while in the command.
The sort criteria can also be changed while slabtop is running by pressing the associated character. character description header a number of active objects ACTIVE b objects per slab OBJ/SLAB c cache size CACHE SIZE l number of slabs SLABS v number of active slabs N/A n name NAME o number of objects OBJS p pages per slab N/A s object size OBJ SIZE u cache utilization USE
or start up the command with the sort option.
c shows the highest cache use.
$ sudo slabtop -s c
