A lot of that seemed to be due to indexing of mail files, which I have turned off (I think). But still the program runs extremely slowly, and I realize it has been hogging one of the two CPUs on my laptop quite reliably. To reproduce, simply start Thunderbird and wait several minutes. High CPU usage does not begin right away. I also do not no if it happens every time, but it happens a large fraction of the time. You had best fix this soon or you will find yourselves losing a lot of users, the program is VERY slow and virtually unusable. Reproducible: Sometimes

More info: As I monitor my system more carefully, I find this behavior starts every time I start Thunderbird, usually within 1 minute of when I start it. It happened at least a dozen times today. Also, memory usage increases. I watched it grow by 100MB per minute; I stopped it when it reached 800MB. Regarding your request that I go through the above list of steps, here is what I have found so far. 1. My tbird profile is on my computer, not on a network drive. 2. I am not allowed to turn off my anti-virus software, says my employer. I have not changed that software lately, although it may be subject to automatic updates. 4. I do have a gmail account, but could not figure out what was meant by unsubscribing from the All Mail folder. What I did was to delete the gmail account from tbird and restart, and the problem was still there. 6. I don't use newsgroups 7. I don't use a calendar This is all I have time for now. What I do observe is that now tbird is NOT going into this CPU hogging mode on me, i.e., after two tries I cannot replicate the problem. I wonder if it has finished indexing a folder. I will note that the remaining steps listed look very time consuming for me to take on. Perhaps it would be more helpful if there was a way of turning on logging of what threads are active at any given time and what they are doing. Obviously some thread is out of control. Perhaps this is what #11 does. If the problem comes back, I will try it.

I'm going to take comment 2 "... if the problem comes back" as WFM. If you still see speed problems, please finish out the wiki document, and consider some of these perf bugs https://bugzilla.mozilla.org/buglist.cgi?type1-0-0=substring&keywords=perf&keywords_type=allwords&field0-0-0=short_desc&bug_severity=blocker&bug_severity=critical&bug_severity=major&bug_severity=normal&type0-0-1=substring&field0-0-1=keywords&type1-0-1=allwordssubstr&resolution=---&classification=Client%20Software&classification=Components&query_format=advanced&type0-0-0=anywordssubstr&component=General&field1-0-0=short_desc&product=MailNews%20Core&product=Thunderbird&field1-0-1=short_desc
