I haven't done any extensive testing as yet but repeating what I was doing previously as a 'litmus test' - launch gnome, open a terminal, launch glxgears, (1) drag glxgears window, (2) add gnome 'Network Monitor' applet, (3) add 'System Monitor' applet with 'Harddisk' enabled as a 'Monitored Resource'. So far I'm seeing what seems to be identical behaviour: (1) Huge lag when I commence dragging glxgears window, typ. 1-2 seconds (2) glxgears stutters at 2Hz matching update rate of applet (3) ditto (1) manifests in two ways - window drags but glxgears freezes, and, more severely, window freezes where it is (stops both updating and following cursor). So far while launching/using evolution, epiphany, etc. I see stalls that look pretty similar to 6.x behaviour. Just thought I'd check in in case there are any suggestions at this point. If not I'll proceed with recompiling ports and preparing test kernels. Wayne
