As of v24.5, running on Ubuntu 13.10 (64bit) with Openbox, I no longer see gettimeofday calls in the strace output. TB is still polling like mad, but is at least efficiency polling. From an strace output like above, I now see:
(11.6%) futex (27.4%) poll ( 4.0%) read (45.3%) recvfrom (11.7%) writev And no gettimeofday. So, from the reporter, who has unfortunately changed the desktop he uses (see comments 16, 17, and 18), I no longer see this. Meanwhile, we still need input from someone running Gnome and Unity, I think. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to thunderbird in Ubuntu. https://bugs.launchpad.net/bugs/109943 Title: Thunderbird: high CPU usage from progress bars Status in Mozilla Thunderbird Mail and News: Confirmed Status in “thunderbird” package in Ubuntu: Confirmed Bug description: Binary package hint: mozilla-thunderbird When sending a simple and short email with Thunderbird via SMTP the CPU is used intensively. This seems not to be necessary. If the sending failed and an corresponding error message dialog appears, the CPU is still being used. When pressing ok to close the error dialog the CPU is fine. This suggests it might be related specifically to the progress bar. Such behavior is especially annoying on a laptop where you can hear the CPU usage because of a starting fan.
