Subject: if we're able to use large page allocators, try and place at least
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=210a7536047638d0b87ab2abc3592e72fa1419ca;p=openbsd

if we're able to use large page allocators, try and place at least
8 items on a page. this reduces the number of allocator operations
we have to do per item on large items.
