I suspect you have a much more general problem on your hands. Just
tweaking the VFS or mmap() code likely isn't going to cut it.

I guess we'll see what you come up with next, but this email was really

It has absolutely not been tested nor reviewed enough. <fud>I hope the
performance gains stick around once more of the bugs are gone.</fud>
