My understanding of the performance issues there are that they are not related to what's in the cache, at least not after the first run, since we will preheat the cache for processes after we know what pages are typically in use. This was true for 10.4, but no longer in 10.5 afaik (see rdar://problem/5139360) . For the non-Apple people: my bug report about the fact that the /var/ vm/app_profile/ directory was never cleaned up under 10.4 (which led to quite a lot of disk usage when performing daily overnight regression testing of a compiler testsuite), was closed with the comment: "There are no application profiles on Leopard. Similar (or better) performance was achieved by using a more flexible read-ahead strategy." This email sent to site_archiver@lists.apple.com
