I was digging through the darwin kernel lists, and did some cursory searches on developer.apple.com, but I didn't find the answer. My question is , does the kernel turn to dynamic_pager every time it swaps pages in and out, or does dynamic_pager simply manage the swap file(s) and grow/shrink them based on usage by the kernel? The reason I ask is that it would seem a large performance penalty to have to context switch out to a user-space daemon for every page in/out request. Not only would you be contesting with page swaps, but you would further be slowed down by expensive context switching from kernel to user space.
