User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/121.0.0.0 Safari/537.36 Herring/90.1.1757.9

Steps to reproduce:

Anything. Writing an email, deleting emails, sending emails. It doesn't matter, everything is super slow.

Actual results:

Clearing out a folder 200 emails at a time takes almost 3 minutes. Switching to the next email takes almost 15 seconds. All this started about a week ago. Prior to that, there were no problems at all.

Expected results:

It should be near instant, as it was prior to a week ago.
Running Version 115.7.0 (64 bit). Says it's up to date.

Does problem go away?

I did start Thunderbird in Troubleshooting mode, and there was no difference. I don't think the issue is with windows, as Firefox, Chrome, and several other apps I use are completely unaffected.

I don't have any addons installed in Thunderbird, never needed them. I use Thunderbird for email only...I don't use any of its extended capabilities.

It doesn't matter that you don't see other apps unaffected.

I have had the exact issue, starting on Monday, Feb. 19th. Nothing changed between Friday when it was working perfectly and Monday when it was absolutely not. There were several times that I would close the program because absolutely everything about it was painfully slow, and after doing so, a crash reporter would come up. It would close successfully, but then the crash reporter window would be open in the background. I probably submitted 8 or so crash reports. I was getting memory issues last week so I went and cleaned out all the cache files, deleted some things, and changed the folders I was syncing with Gmail. However, I have another account connected that is a completely different server/provider, and it is just as bad.

If I search for an email address or key word, it takes so long before doing anything - if at all - that I have stopped using the feature. Today I have mainly used the online accounts because everything - EVERYTHING - is so bogged down that itis costing me time. I have access to both emails with no issues in Chrome. I opened it after reading this bug to see if there was any difference. None at all. It said it was downloading message 1 of 10 for about a minute and a half. I turned it to offline, cancelled the download, and waited for a bit for the home page to open.

As I was writing this, I decided to open Thunderbird to see how long it took to open. It was doing nothing so I clicked on the icon again after about 20 seconds as the opening screen hasn't been taking long to come up. I got the message that an instance was already running. I "quit Thunderbird", and went to my task manager. There were two instances running that I had to force quit. I opened the program again, and it opened right up. I was very encouraged when the three messages from Mozilla and Bugzilla opened up almost instantly. Then, when I clicked on the email that was unopened from a client, after about 10 seconds or so, it displayed with a bunch of gibberish. It was still showing as unread, so I clicked on one of the Mozilla emails, and tried opening the other email again. I counted. 25 seconds. After about 15 seconds, it displayed the headers, which quickly disappeared. At the end of the 25 seconds, I got the gibberish again.

I have 32 GB of RAM. The program is not using an unusual amount of memory - CPU, GPU, or RAM.

Other than the crashes, this is EXACTLY what is going on with my system. One day it works great, next day it is f**ked. Now I have to go looking for another email client unless this gets fixed ASAP.

It collects performance data. The description and steps are hopefully clear. If not, please PM me and we can discuss. At the end, you supply a URL which points to the collected data

I have the same problem on multiple instances of TB 115.11.0 (64-bit) on both Linux and Windows-11. This has been happening for sometime. I own my own domain and my hosting provider has also checked the (IMAP) mail server configuration on their end without any improvement. The problem is very apparent when encoding embedded (versus attached) pictures or graphics. Sometimes taking as long as 3 minutes to send an 11MB email, the a shorter - but significant - wait while the email is copied to the sent folder. I have gig-fiber internet connection and the ping to my mail server is less than 100ms. I have started to look for other email options at this point.

One of the workarounds for the major issue fixed in beta, is to NOT have the Inbox or Sent folder selected when messages are being downloaded or sent.

Sam,
Harald,
Can you try that as a test?

The way my hosting provider (DreamHost) configures the mail accounts is that all folders (even sent) are subordinate to Inbox.

Inbox
|-->Drafts
|-->Sent
|-->Trash
*-->etc.

Sending with "other folders" selected - meaning not specifically Inbox or Sent - yields the same results. Is there another way to get the test results you're looking for?

128 will be available later this week.

I don't think so.
