Description
See net.pf.states_hashsize
in pf(4):
Size of hash tables that store states. Should be power of 2. Default value is 131072.
States are locked per hashrow, so if there are a lot of them in the same row they contend on the same lock (and that’s also the lock needed when exporting state information to userspace). One or two states per row is ideal.

The original description here doesn't match what was committed. The commit is for net.pf.states_hashsize
but the original description has net.pf.source_nodes_hashsize
. I went by what was committed since that seemed to be the intent.
- Description updated (diff)
Indeed I meant net.pf.states_hashsize
.

Appears to be using the expected value based on the given calculation.
