User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:86.0) Gecko/20100101 Firefox/86.0 Steps to reproduce: I am a long time user of TB, I think more than 20yrs now and I never thought to switch to another mail cliend even as I have an Office 365 home subscription with Outlook. So I am still continueing to use TB, but since a few years it is annoying because of performance of TB user interface. It gets worse with every new update, specially in the last monthes I see more and more performance issues. I have set up several mail accounts in TB and my mailarchive is about 20-30GB in size, even keeping very old emails if they are still interesting/important. I have filters to sort incomming mails in douzens of folders, so call me a TB power user. I am using TB on mainly two systems, one is a small laptop using an 7 years old Atom based Pentium CPU, the other is a highend Xeon workstations with 8 cores, hyperthreading, 64gb RAM, and both are using big and fast SSD where also the mailarchive is stored. I have not installed any addon in TB. Actual results: TB is very slow in user interface. It does compresessing folders while checking for new emails. It does compressing folders while using TB actively. It checks several email accounts at the same time and complaining that automatic filters can not work because folder is in use. TB is very busy with itself while I want to use it, it does not react to on mouse clicks, not on the small laptop, and not on the Xeon workstation. If I try to answer an email while it does all these backround tasks, it is very often impossible to write into the message, the characters only displayed after seconds to minutes, etc. While answering a mail, the main window appears in the front of the mail window and no reaction to switch back to the message window, and a lot of such annoying things. Manually moving mails to another folder is also complaining often while backround activities like compression or mailchecking are running. Some times TB is like unuseable. In Windows taskmanager I observe that there is only one process, while Firefox uses several processes/processor cores which could spread over 4 to 16 cores on my computers. Expected results: Impprove performance massively, by using multithreading, make backround tasks like folder compression in the backround while TB is idle. Stop backround tasks like compressing while email checking, while user interaction. Avoid compression of folders which have not been touched since last compression. Make TB more performant, make it more useable again.
