Thunderbird very slow to send emails (Fedora)
Hi I was using TB 142 without problems. When upgrading to 143 ou 144.B4 I have problems sending mails to all users after some times. Usually the first mails are sent immediatly but after around 10 mails, I have very slow response (varies from 5 sec to more than 1 minute and sometimes timeout). Usually quitting TB solves the problem but this is very annoying. I went back to 140LTS and sems to have no longer this problem. This was tested on many diffrent networks. I am running under Fedora release 42
Thanks

Thanks for the answer. I still had the problem with my TB 143 profile last friday. After 7 mails sent it took 30 seconds to send mails. Today I set up the profiling parameters and tested more than 50 mails with no problem. I'll check further today and start the recording if problem occurs again

Restarted the process with daily 145.0a1 (2025-10-12) (64 bits) I soon had the problem of slow sending, ending with a timeout. The link of the capture is: https://share.firefox.dev/3WzgKkl
