I've been monitoring top during the update process and have noticed a few things. frequent CPU users are: synaptic xorg dpkg apt-check gconftool-2 There are usually two processes for synaptic, they both seem to spend most of their time waiting or idle, but sometimes spike. Gconftool-2, when running, uses near 100% cpu, and was the only single process I could point to as having used massive amounts of the CPU.
However, during the most severe spikes, Top actually froze itself for anywhere from 4 to 20 seconds, leaving me uncertain what was going on during those periods. The interesting thing is that either all live updating items were paused/frozen, too, or the CPU did not scale up from 800mhz during this time stretch (in other words it seems like CPU frequency scaling was possibly not responding to the package manager's load, a state which could turn 50% load into 100% load). -- updating near freezes system in extremely nonlinear way https://bugs.launchpad.net/bugs/273829 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
