It does not depend on IMAP server. 1000 folders. When SquirrelMail
generates mailbox listing, it issues one IMAP command for any subscribed
IMAP folder. Magic point where processing of one big IMAP response in PHP
is faster than issuing one command for any IMAP folder is somewhere near
20 folders. If user has more than 20 folders, mailbox listing is not done
in optimal way. Now imagine how not optimal it can be with 1000 folders or
do little math. 1000 / 20 = ?
Correct fix is to fix mailbox cache generation.
Hrm, makes sense. I have an account with just under 100 folders (just under 2 GB of mail storage), and everything is quick (less than 5 seconds to generate mailbox list and initial page of inbox). Figured that would scale out to 1000 as that would still fall within the 60s deadline we have for php scripts. But, guess it's not a linear scale.
