This problem has been driving me nuts. It gets worse over time, suggesting a leak someplace. Other evidence for a leak, the unity-panel- service heap grows from 21MB on boot to 350MB or more after a few days of uptime.
I profiled the system several times using sysprof (see attached profile). The profiles consistently show that almost all time is spent in a pair of gobject methods (handlers_find() and handler_lookup()). The code in these methods traverses a linked list of 'handlers', suggesting that those lists are growing large. Some cursory poking around in gdb confirms that the lists being traversed are very large - at least tens of thousands of elements. I'm not yet sure why they are growing so big or what's in them. ** Attachment added: "unity-panel-service.sysprof" https://bugs.launchpad.net/ubuntu/+source/unity/+bug/1199877/+attachment/3805880/+files/unity-panel-service.sysprof -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1199877 Title: unity-panel-service pegs one of my CPUs at 100% To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-power-consumption/+bug/1199877/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
