I don't know anything about "ZAP code" but I do know that CPU caches are only so large and there can be many caches for the same data since each CPU has its own cache. Some of us do actual computing using these same CPUs so it would be nice if they weren't entirely consumed by the filesystem. Current application performance on today's hardware absolutely sucks as compared to its theroretical potential. Let's try to improve that performance rather than adding more cache thrashing, leading to more wait states.
