hi I have two questions: 1) is kmem_alloc_wait() expensive operation? I believe it's not very cheap looking at the code but I want confirmation 2) is there a support for memory pools in FreeBSD? to give you a little background why I am asking this. In NetBSD Andrew Doran claims that replacing allocation from a memory submap with an allocation from a memory pool for exec*() args he can speedup exec*() by ~25% I wonder if this applies to FreeBSD too so I am investigating it a little. thnx! roman
