User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6b) Gecko/20031122 Firebird/0.7+ Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6b) Gecko/20031122 Firebird/0.7+ I'm using an IMAP mail folder and everytime I launch thunderbird to check for new mail, and if it indeed found new mail, it takes quite some time and the system freezes for a short while, the harddisk rattling loudly. I guess thunderbird rearranges its mail datafiles, but it takes too much time and is quite annoying, for instance when burning a cd at the same time. It also keeps me from opening thunderbird to quickly check my mail. Reproducible: Always Steps to Reproduce: 1. send mail to self 2. open thunderbird 3. watch your harddisk rattle a while maybe this is solely the case for IMAP folders, I don't know.
POP3 retrieval is also very slow.
I've just logged bug 241793 on the MailNews component which sounds quite similar to this one. I ran the free www.sysinternals.com FileMon tool and you can see what is happening in terms of disk activity during the "harddisk rattling" I experience. It may be worth comparing what you see.
There really should be done something about it. I have no problems with this on my laptop. I just installed thunderbird on my dad's computer, (he has a POP account), and there it takes ages to delete a message, yet flushing the trash folder is done in a jiffy.
I see this too on my desktop. When I start Thunderbird, it sits there unresponsive for minutes. Then it will not access my mail accounts. The login prompt never is displayed. It is fine on my laptop. I did a reinstall, but no joy.
Confirm this behaviour on: version 1.0.6 (20050716) All operations outside selecting a message ie. opening, deleting, moving folders etc. almost hang the computer for the time it takes to complete the operation. Can not change windows, can not select another message while one is "opening" etc. Started after I switched to a system with 64bit AMD processor, everything else remained the same including the OS. Have tried to reinstall and update from 1.0.4 but no avail.
things like this can often be caused by virus checking programs.
The comment about virus checking has no bearing on what I'm seeing as there is none running. This problem began showing up around 1-2 weeks ago and is so severe I've gone back to Mozilla. Using the recommended Filemon program I seem many repeated file access patterns. This is a show stopper for using Thunderbird, as it can take 30 seconds to load a message from an IMAP server and display it, where Mozilla is near instantaneous.
I made an ticket to F-Secure to check whether they could be causing this slowness on my personal case. They said that this is a common problem when the mailfile is being accessed by the mail client and virus scanner. In case of POP3 I did put the mail directory to be exluded from real-time scanning and the problem went away.
Alas, I too am having this problem now. Even after revertin to older versions of Thunderbird which had worked fine. Symptom is about 10-15 seconds of hard disk activity each time I open a message. It behaves as if, perhaps, the mail summary file is corrupt (even though I deleted the summary files and allowed rebuild and had same symptom), and that it does not contain valid 'pointers' to the data file's offset for the message, so that the data file must be linearly searched each time. That's how it seems to be, anyway. Is it possible that a recent alpha build will have corrupted the expected syntax/offsets in my current datafiles? If someone familar with the inards of the mail filesystem can suggest tests, I'd be happy to help diagnose this one.
Correction: The problem does not occur when I revert to Thunderbird 1.0.7. But any of my recent 1.5/1.6 alpha installers that I try do have this problme; so the issue appears not as much related to this bug (reported against MUCH earlier versions), but more related to the new 1.5+ builds.
if the summary file was getting regenerated, you'd see a status message to that effect. This kind of issue almost always turns out to be a virus checker issue, or an issue with some program that's trapping file i/o. I run debug trunk builds all the time with pop3 messages and I never see this.
I am no longer have this problem with TB 1.5.x release builds.. I elect that this be marked FIXED.
I have the same problem as most: Thunderbird becomes unresponsive immediately after start. The older Thunderbird 1.0.7 was faster. If I disable my virus software the problem disappears.

Whiteboard: possible workaround: set virus scanner to exclude the mail directory
http://kb.mozillazine.org/Thunderbird_:_Issues_:_Folder_Being_Processed bullet items are relevant to some of the above comments - especially those going back a few years. matthew redekopp in comment #13: > I have the same problem as most: Thunderbird becomes unresponsive immediately > after start.

Summary: Slow mail retrieval → Slow mail retrieval directing more than one account to the same folder.
Reporter: "I think it was solved by saving the different mail accounts to different folders instead of all to the same folder....I actually cannot remember what the exact problem was. I also do not use Thunderbird (gmail just does it for me) anymore so I can't really tell." closing invalid as there is no testcase for original report and others were antivirus related. if anyone still sees a problem on a current release please file a new bug.
