Confirmed on quantal. At the tame time, thunderbird is triggering
constant redraws as seen in the Compiz Benchmark plugin. Killing and
restarting thunderbird fixed it for me.

I am having the same problem. Thunderbird pegs one processor at near
100%. The instructions in comment #11 did not fix it. Activity Manager
sometimes shows no activity for several minutes, but the CPU use is
still high. Probably more important is that it just keeps cycling
between syncing Sent M
Also witnessing the problem. I guess so few people noticed it is that it
might be somehow associated to users who have several email accounts
configured (I have 11 accounts configured in my TB profile).
Opening the activity window shows that a lot (and probably too many) of
sync operations are be
I have the same problem on 12.04 with Thunderbird 16.0.1.
After starting, CPU spikes up to ~60% and stays there for around 20
minutes.
Switching to offline mode immediately stops the problem, switching it
back on resumes it, so yes, it is probably email syncing or something
related.
There is a g
I just tried thunderbird 16.0.1. I get the similar numbers as David:

I do not see this.

Those show up. I do not
I was having this issue aswell with Ubuntu 12.04 and Thunderbird 15.0.1.
The solution described in comment #14 works for me.

I was also having this issue with Ubuntu 12.04 and encrypted home

Had the exact same issue as comment #11 including log spamming and can
confirm that deleting the empty file 'global-messages-db.sqlite-journal'
in my Thunderbird account folder resolved the issue.
This was under Ubuntu 12.04 with Thunderbird 14 and encrypted home
directory.

Regression or not, it's still an annoying bug.
I'm attaching performance data from my older computer, where this is a
nuisance. In the two minutes I let Thunderbird run, it fetched less than
1000 emails - which means just a few emails per second (which is not
good IMO!).
The latest comment indica
Some further info: My syslog was geting spammed with eCryptfs messages
as per https://bugs.launchpad.net/ecryptfs/+bug/911507, but only when
Thunderbird was in online mode.
The culprit was a zero length global-messages-db.sqlite-journal file
under .thunderbird. I'd copied my .thunderbird directory

that due to the "regression-update" tag those comments are reaching the
SRU team so I'm dropping that and unassigning the desktop team on those

I only see this when working online. If I change to working offline, the
CPU usage drops to idle. I f I re-enable working online, the CPU spikes
again.
It appears to be related to loading/indexing mail from remote IMAP
mailserver that contains a lot of mail on a new install that hasn't

I possibly have this issue as well. however, after letting thunderbird
run for 18 hours (!) of cpu time the cpu usage dropped to reasonable
levels. after exiting and restarting thunderbird the usage goes up again
for some minutes but then normalizes much faster...

To me, it seems related to fetching new messages. I have a lot of
messages in my mailbox, and in many different folders. When doing the
initial sync for a new setup, it is very CPU intensive.

I have the same issue with Ubuntu 12.04 LTS 64 bit on a MacBook Pro 8,1
(late 2011). Whenever I have Thunderbird open, my CPU usage shoots up to
about 20%, my laptop heats up and my battery gets drained atleast twice
or even thrice as quickly. Makes Thunderbird unusable on my laptop.

I am seeing 22-25% CPU usage by Thunderbird. When TB is open, compiz is
also using around 20%, this drops to around 1% when TB is closed.

I can confirm this. It just does it occasionally, so it's not really
reproducible. I had the issue a few days ago, then it settled down, and
now it's back again.
