Hi James, When you measured that, did the system you used have sufficient openat support? If not, you probably saw the performance penalty of the openat/fstatat/etc. wrapper functions that simulate the syscalls -- probably via /proc/self/fd/%d/%s. If you run timings on a losing kernel/libc combination, you should expect a performance penalty. Jim
