I'm having this issue too, with x86-64 Lucid. I'm on a 1.83Ghz Core2 Duo with 1.5gigs of ram, 2 gigs of swap, and a fast SATA hard drive.
This feels very much what would happen with an old computer when DMA was disabled... but of course this is a SATA hard drive, and I don't know how to confirm if it's configured properly. It's plenty fast after a reboot, but at some point, it just gets barely usable. At apt-get upgrade will generally trigger it. Once it's there, it seems like a little hard drive IO and CPU just don't mix any more (as if DMA was disabled) -- Heavy Disk I/O harms desktop responsiveness https://bugs.launchpad.net/bugs/131094 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
