I've not looked into F15 disk performance, and as I never plan to run FC15 I doubt I ever will. I'm skipping this release. I can't specifically say FC15 has that problem but its something I've seen chasing down I/O performance problems on systems. It doesn't take much to give a disk a pile of extra seeks to do and that hurts because seek times haven't changed in years and are now relatively very expensive. > So why not bring it (them) into the light and knock around a bit ? > Btw, would that apply to kernel daemons as well ? I've no interest in Fedora 15 and pinning it down is a fairly big job involving various re-installs. > Also it'd be interesting to know if you kept the OS default partitioning scheme > (in which case the Fedora install would likely have an LVM layer the Ubuntu one > would not.) > > Yes, defaults. Could be. Still fair benchmark because Fedora configures the disks that way default. Easy way to check - go do two installs on a box similar to the Phoronix one and see what you get if you want to find out.
