Thank you for reading and hopefully answering soon. :)
How much RAM do you have?
Also, if you look at the Task Manager, what's the memory demand coming
from Seamonkey?
What extensions do you have active, and do you run any mail processing
filters?
It could be that there may be some sort of script that's active,
although I've never seen anything hammer just one core.
I've long suspected that there's some sort of memory leak issue in
Seamonkey, but I've never gotten any further than that. I know that
when I leave it on for a long time (especially overnight) I often see
relative high memory use (sometimes, in excess of 2 GB), really slow
performance, and more frequent warnings of timeouts on scripts. A
restart of Seamonkey normally clears that problem.
If I take a look at about:memory, there's indications of active
scripting from message filters in the mail client, as well as scripting
from previously-opened tabs in the browser. I've found that sometimes
running a "Free Memory" can lower memory usage, and sometimes improve
performance a little.
I know that a couple of months ago, I was filling in a form on a morning
after I had left Seamonkey open overnight, and this was one of those
forms that launches a script for every single field. Everything was
really slow, and by the time I got to the end of the form, I was getting
scripting timeout errors, and it was pretty painful. The only reason I
didn't restart Seamonkey was that I didn't want to start the form over
from the beginning again.
I will note that I'm a long-time user of NoScript and uBlock Origin (and
Adblock Plus before that), and it seems that uBlock may be the culprit
for me, especially since I have a lot of user-crafted rules (I tend to
block annoying graphics that I don't want to see, even if they're not ads).
All that said, I've noticed that since I upgraded to 2.53.3, I notice a
lot less performance issues, especially if I leave Seamonkey active
overnight.
