kmem_cache_shrink() will explicitly sort the partial lists to put the partial pages in that order.Realized that I’d do "echo 1 > /sys/kernel/slab/dentry/shrink” to sort the list explicitly. After that, the numbers become: N = 10000 -> diff = 7.1 % N = 20000 -> diff = 5.7 % N = 25000 -> diff = 5.4 % So, expecting ~5-7% difference after shrinking.
That still looks ok to me.
