how many emails in the inbox or folder in question

i generally find thunderbird for example can handle an inbox of up to 20,000 emails in it without much issue (assuming half decent network connection etc)

after that it slows down

outlook don't even use if more then 200

rarely see a 40 second delay unless actually doing a physical search on the server side then rebuilding would become an issue?

it's usually best to divert large inbox's to other subfolders if possible.

might help?

Happy Wednesday !!! Thanks - paul

If *this* is the problem you saw (and not the 2 hour delay mentioned further in the thread), you can get a hint where the problem lies if you see a 40s gap in the session logs: it will tell you who was doing what when the pause happened (e.g. during authentication? During LIST fetch? During message fetch?)

For example, if dovecot was busy mulching through a large INBOX rebuilding indices, I can see how it can chew up 40s under some circumstances.
