Yeah, that is an interesting point.
What cacheing can the kernel do? The filesystem is multi-hosted (at least in possibility) yes? So surely the kernel has to go right back to the filesystem every time to make sure it gets current state information. What atime setting does the filesystem have? Anything other than noatime will definitely require the kernel to go right back to the disk blocks at least some of the time. The bug report describes what PHP does; there's lots of discussion of the cacheing it does and doesn't do. In particular it does cache between [HTTP] requests, because as it says what's the point of a cache otherwise. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
