Thunderbird on Tumbleweed - very high load

English Applications
1

This is on a completely fresh installation of Tumbleweed, Packman activated and Thunderbird 52.1.0 (64-bit) installed from there.

/home has been used from my alternative Fedora installation on a different partition, UID identical on both Linux versions.

Thunderbird starts up, connects fine to the mail server, lets me read and send mails, but load is extremely high; htop shows fluctuations between 45% and 80%, thus making the fans spin pretty high on the Lenovo X1 Carbon (3rd gen.).

I had initially assumed there would be some kind of indexing etc. involved, but since machine and SDD are pretty fast, this should be over after 30 min. that I kept it running.

Any ideas? What more information would you need to find the reason of this high load?

TIA.

OK, I found a solution after completely abusing my Google-Fu:

Now, this is from 2013 and the default is still 300000. Changing this to 3000000 indeed completely made the high load go away. Now it’s idling and leaves my fans off.

Wouldn’t it make sense to change the default?

That is a question you should ask at Mozilla.
