And in part because they don't give a damn. It's really hard to name very many applications where this is likely to give a big enough performance boost to justify dealing with filesystem-dependent optimizations. (Because it's filesystem dependent, you couldn't even drive it off a configuration switch; you'd have to probe at runtime to determine whether there was anything you could do.) As an example: you don't seriously believe that this is the bottleneck for downloading RPM files, do you? regards, tom lane -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
