The comments in the code Colin pointed to say this: * gs_file_read_noatime: * @file: a #GFile * @cancellable: a #GCancellable * @error: a #GError * * Like g_file_read(), but try to avoid updating the file's * access time.

Does opening with noatime really make a measurable difference (assuming it worked)? I suspect not since what we have now is 2 syscalls. It would probably be faster to load icons without trying to set NOATIME. Thanks, -Steve -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
