The limited data so far suggests it isn't that important, unless you're doing filemtime(), filesize() together in order over hundreds or thousands of files. In that case, calling stat() would be better, though by how much is unclear. Or using SplFileInfo(). (I have no idea if it uses the stat cache or loads the stat data once and just exposes it through methods.) > I mean, are there cases when this cache is still useful in 2025? That is indeed the question. :-) I think so far we can say "not most of the time," but haven't yet figured out all the possible edge cases. --Larry Garfield
