[$] Why glibc's fstat() is slow
jeudi 14 septembre 2023, 18:29 , par LWN.net
The fstat()
system call retrieves some of the metadata — owner, size, protections, timestamps, and so on — associated with an open file descriptor. One might not think of it as a performance-critical system call, but there are workloads that make a lot of fstat() calls; it is not something that should be slowed unnecessarily. As it turns out, though, the GNU C Library (glibc) has been doing exactly that, but a fix is in the works.
