Not horribly important, but whenever KMail checks mail is ‘freezes’ for a bit
and interrupts typing/mouse clicks (just for KMail, rest of system runs
fine).
Would it be hard to make KMail multi-threaded? I’m assuming that’d ‘fix’ the
freezes…
Again, not at all critical, but if it’s easy, I’ll get off my butt and put in
a feature request.

Explain what you are exactly doing so that someone can reproduce it. I think
it is multithreaded already and the mail checking is done via background
job (if I am not totally wrong it is run in another thread) that has
nothing to do with the GUI. But I am not exactly an expert in the internals
of KMail.

This is strange. Do you get hundreds of mails in 15 minutes?
Could you run "htop" in a terminal so that you see which program is blocking? It
might be something spawned from kmail or something totally different.

Yeah, due to spikiness of things, I’d guess some mail checks get 200-300
mails, some get 10. The average of ~50+ was over the last 15 day period
(75,000 in 15 days if someone wants to check my maths...).
htop attached of KMail at idle. I had the main window and 3 messages open (=
4 child processes?). During a mail check it climbs to 100% CPU% for the
parent KMail row, the children don’t change at all, sits at 100% until it’s
done (1-3 seconds) and then drops back to ~0% CPU%.
My graphical skills lack, headers are:
PID / USER / PRI / NI / VIRT / RES / SHR / S / CPU% / MEM% / TIME+ / Command /
The 0.7 is CPU%
2119M is VIRT
I don’t know htop well enough, but it’d seems CPU% has to be for a single CPU?
Yeah, gotta be, load average: 0.30, 0.20, 0.14, so it’s not doing anything to
even 1 minute load numbers.

You could use tcpdump and wireshark to see the timeline for example.
You probably don't have the debug package installed, but if it is there you
could enable debugging for kmail and some tdeio like pop3 or imap etc.
Restart kmail and see what the log says.
I don't have any better idea for now.
BTW it's also not clear which protocol you use - POP/IMAP?

We've most likely spent more time than this is worth already, and like you my
best guess is number of messages combined with number of filters.

POP through an always present SSH tunnel.
I was given to understand a decade back by Ingo Kloker
that it was going
to be a major rewrite.
And that’s good enough for me to lay this to rest.
Sounds a bit complex but it all Just Works. 2 mouse
clicks to answer a
message as I am doing now. Whats not to like?
Did you ever do a write up somewhere? I can’t just delete mail (have to have
15 day retention on pretty much everything) but I’ve used most of the tools
you talk about, so I’d like to play with it so to speak.
Thanks All,

Not recent enough to be valid today. Some new spammer shows up and he
soon gets added to the procmail filters, so lets just say its semi
dynamic. I don't retain that stuff more than 48 hours max as its fed to
sa-learn about 1 every morning, moved to a save dir in case a mistake
was made, and if I don't move it from that dir in that 24 hours, the
same script throws it away before copying in the new saved listings. So
spam gets fed to sa-learn and saved, and if I don't move it, its gone
the next day. If its spam, why should I waste time and disk storing it
for 2 weeks?
Some lists I'm on are saved forever and I do have archives back to 2002
of some lists, but many have a 60 day expiry, or less.
