Yes, according to the SLUB docs it is. With yesterday's updates its slowest of all so far. "xterm -e mc" window resize test takes 53 seconds to redraw up to full vertical size. It takes approx. 4 secs already for MC to redraw for the first time. That's just the most obvious to notice. In other apps, delays are noticable, too, e.g. even when deleting/inserting in Claws Mail's own editor. There also has been a Mesa update. -- Fedora release 16 (Verne) - Linux 3.1.0-0.rc5.git0.0.fc16.x86_64 loadavg: 0.33 0.25 0.20 -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
