~$ sudo dmidecode -s bios-version && sudo dmidecode -s bios-release-date A06 02/02/2008 In an attempt to quantify, I run hdparm and gtkperf. They both show large losses in performance. Before: ~$ gtkperf -a Total time: 12.02 ~$ sudo hdparm -tT /dev/sda Timing cached reads: 1674 MB in 2.00 seconds = 837.49 MB/sec Timing buffered disk reads: 64 MB in 3.11 seconds = 20.57 MB/sec After: ~$ gtkperf -a Total time: 40.88 ~$ sudo hdparm -tT /dev/sda Timing cached reads: 442 MB in 2.00 seconds = 221.04 MB/sec Timing buffered disk reads: 62 MB in 3.05 seconds = 20.31 MB/sec -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1189645 Title: 13.04, lag under desktop environments To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/1189645/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
