Bumping this from 39 in Poudriere gives me significant time savings
in some cases due to heavy use of eval/setvar to store information
for all ports (25-30k+) in memory.
Specifically I have a hash_set/hash_isset/hash_get API that uses
eval/setvar to set arbitrary variables. I have it loading one
entry, for every port in the tree, into memory. I added some
calls to hash_set/hash_get (on unrelated-to-ports variables) into
a loop and found that it caused a 25% slowdown. I've realized
that I don't need this data loaded at all but want to bump the
value regardless since Poudriere uses so many vars and can easily
hit this sort of collision slowdown.
This will just let me override it at compile-time without needing
a patch.
It would be nice if this had auto resizing once collisions were
too high.
