Thunderbird Support for help with technical and performance issues (win10)
I have a computer with a 5800X3D, 64 GiB Ram, Samsung 980 Pro M2 SSD, Windows 10 64 Bit with Thunderbird 138.0 (64-bit).
I changed to MailDir format because I have over 250.000 emails and the mbox format was very, very slow. I save all emails to the SSD to not have to check them again.
It works, but Thunderbird regularly freezes for around 1–2 minutes and isn't reactive anymore. The Task Manager shows that one core is used completely.
Can you look into the Thunderbird behavior if more than 200k emails are present? Thunderbird is fine if you just have a few emails. Maybe you can pre-cache it and/or use more than one core?
I cannot upgrade much more on the hardware front. Might be an even faster SSD, but then the vertical scaling would hit a wall.

There are not plans to provide more than one core. Large message stores are already tested, so we wouldn't do additional testing.
If it freezes for 1-2 minutes, and responsiveness does not return, then there may be a bad folder.
Also, many issues tend to be specific to the user's environment, so stepping through https://wiki.mozilla.org/Thunderbird:Testing:Memory_Usage_Problems will be important. Please post your results.
