Description of problem: Sending an email with thunderbird takes a lot of processing time. I'm not really sure if this is even a bug, it just seems far too high for transferring a couple of lines of plaintext. I'm not sure if it has always been like this, but I've noticed it a lot in the last few months. A lot of the time seems to be taken up with a progress bar, and a message saying that it's saving the message to the Sent Mail folder (On a side note, a lot of the time this saving part fails first time around when sending a message from my google apps account, not sure about from other accounts). Version-Release number of selected component (if applicable): 10.0.1 How reproducible: 100% Steps to Reproduce: 1. Write email in Thunderbird 2. Send email 3. look at CPU usage in a system monitor Actual results: Thunderbird seems to be using a huge amount of processing time. Expected results: Presumably sending an email wouldn't take this amount of processor time for so long. Additional info: If there's any more info I can provide, I'd be happy to!
After further observation, I think it might not be thunderbird directly that's hogging the CPU time: When an email is sent 'inline' at the end of another message, it doesn't happen. When an email is sent in a new window (e.g. a new message, or a reply popped out from having been 'inline'), then it happens. The main difference I can see between the two, are the two scrolling progress bars: one at the bottom of the message window, and a larger one in the middle of the sending status window. Could it be these that are causing the load? Is this even considered a bug/problem?
Please check addon manager if you have any addon installed.
You may also try to run thunderbird in safe mode by: thunderbird -safe-mode or see: https://fedoraproject.org/wiki/Debugging_guidelines_for_Mozilla_products#Figuring_out_what_is_responsible_for_crash for further explanation.
Do you still encounter this problem? If Thunderbird consumes 100% of CPU and UI freeze for couple of seconds it sounds like a bug.
I haven't used Thunderbird in a while: I've spent the last couple of months hopping between different mail clients. I'll give it a try now and report back!
(In reply to comment #4) > Do you still encounter this problem? If Thunderbird consumes 100% of CPU and > UI freeze for couple of seconds it sounds like a bug. I just tried on Thunderbird 14, and I didn't experience this. I guess whatever was causing it has been fixed. Thanks! :)
Okay, thanks for letting me know.
