Details

(Keywords: perf, Whiteboard: [antivirus: Defender (aka Virus & Threat Protection)])

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.89 Safari/537.36

Steps to reproduce:

Typing / scrolling / anything is extremely slow - takes multiple seconds to scroll or follow up on typing. Generally the whole UX freezes.

I was trying to find a way to record and share logs or share profiling session, but I couldn't find it. Please let me know how best I can help with this bug, as it is lacking details.

I noticed that, especially now (after being offline for two weeks), while messages are being downloaded (337 out of 345), Thunderbird is EXTREMELY sluggish.

I tried disabling add-ons, I was trying to enable and disable hardware acceleration. My inbox is fairly large (46055 messages, 3.2GB size on disk), but the total profile (including subdirectories in imap) has over 15GB. Two biggest files in
C:\Users\psla\AppData\Roaming\Thunderbird\Profiles\werj21zt.default\ImapMail\mail.sepio.pl have 3.4 and 3.2GB (inbox, and one subdirectory).
The profile is located on an SSD drive.

Once the messages were downloaded, the UX stopped freezing.

While this may be jumping to conclusions, but it feels like something is blocking a UI thread while donwloading these messages (indexer?)

Actual results:

Multiple seconds to display character, to show menu, to scroll; while messages are being downloaded from IMAP.

Expected results:

Typing should be immediate and firefox shouldn't freeze.

Thanks Wayne. I will get familiar with that info - I use Windows Defender in its default configuration.

Do you seen an improvement after excluding the Thunderbird profile?

Flags: needinfo?(psla)
Whiteboard: [closeme 2020-08-22]

Hi Wayne. I haven't gotten back to you, because it's somewhat hard to reproduce. When receiving one email, it's very hard to notice this issue - but when I was receiving 300 emails, it was very pronounced. I think I will make a copy of INBOX, and restore that copy after a week - forcing download of multiple messages. Let me know if there is any other way to mimic the download.
(alternatively, maybe I will simply send myself some 100-300 messages...)
Bear with me, I will update this ticket once I get a consistent repro whether excluding thunderbird profile from defender helped.

That or just remove the entire Inbox file?

Summary: Thunderbird extremely slow while typing or doing anything (while indexing?) → Thunderbird extremely slow typing or doing anything when downloading messages (and indexing?)

My assumption (potentially wrong) is that if it is defender slowing things down/freezing, then the slowdown is a function of the size of the inbox -- so if I removed the inbox file, it would become tiny, and defender would be quick when scanning it and the freezes might not be noticeable.

But it's easy to test, so I might as well do it. :) Pls bear with me, I have a lot on my plate right now.

After excluding %AppData%\Thunderbird from Defender (aka Virus & Threat Protection) the freezes went away, and the sync is much faster.

At this point I believe this bug can be closed - but I feel compelled to ask (once again thanks for your awesome help, and I really appreciate Thunderbird as a (free) product!): is there something that Thunderbird could be doing differently to avoid the problem, or minimize it? E.g. journalling/batching writes to the file, or splitting file to smaller chunks? Or why is it freezing the UX? I would expect that defender would run in background, and no operation would run on the UX thread - e.g. saving drafts or anything else that needs access to the file on disk should run outside of the main thread, and the UX should be responsive.

For the future generations: to exclude this from defender on Windows 10, with the new fancy UI:

  1. Go to "windows security"
  2. Click "virus & threat protection"
  3. Click "manage settings"
  4. Find "exclusions", and click "add or remove exclusions"
  5. "Add an exclusion", "folder",
  6. %AppData%\Thunderbird

Thanks for the update, and your steps to mitigate.
Yes, there are definitely product changes that could help.
