Oh yeah there are lots of tips and tricks for optimizing performance. Some standard stuff to check:
* Any processes gobbling cpu, memory, or disk IO? (top, ps, nmon, atop, free -m, nice/ionice, etc.) * Got any unusual cron jobs set up? * Is it swapping to disk? (top or vmstat should show this, or the %wa number in top) * Can you repro it in a guest session? * Can you repro it on a Live CD? * Any firmware updates for your motherboard? dmesg is a good thing to check; especially keep an eye on that GPU lock message. If you're able to correlate that to when the sluggishness happens that would be quite interesting. If the message is there when the system is working fine, that would reinforce my guess that the bugs are separate. Hardware's also a possibility. Switching to a SSD helped a ton with performance just in general, and particularly with swapping. Increasing ram can help in some situations. On laptops a failing power supply can cause weird bugs (esp. if it's fine when on battery). Good luck, let me know what you find. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/826504 Title: System becomes extremely sluggish To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/826504/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
