Is this still true? What is the reason for this? And: Does
any odd hashtable size work as well as other odd hash tables sizes
in the same order of magnitude?
changing conntrack_max is not chaning the hash bucket count, that change
can only be done in the code or as a module parameter at module load
time.
Sure, I meant odd hash bucket counts of course, so is this
FAQ still accurate?
as far as I know.
None of this is :) hash_buckets can be changed at runtime through the
sysfs module parameter and the size can be chosen arbitary, in fact
the current -git tree will round it up to the next multiple of
PAGE_SIZE / (sizeof(struct hlist_head)) to avoid memory wastage.
not knowing what that sizeof evaluates to, has anyone checked to make sure that
this doesn't cause pathalogical performance or distribution problems with this
hash?
