11 P4's are slow at syscalls aren't they? I'm pretty sure that Linus has commented
12 on lkml and dri-dev about this issue. Maybe they've addressed this in redhat's kernel?
13 Maybe the increased time is for a good reason?

15 28 microseconds is what %age of a typical web server connection processing time?

20 Yes, but one benchmark measured by one person with one comment of "what I want
21 gentoo for is a web server" is hardly a basis for deciding "best performance
22 kernel" is it? It's not even a basis for deciding what's best for a server.
