Dear Folks,
Using head of imaptest with dovecot 2.1, I am attempting to put a heavy load on the server, with insufficient success.
I made 15000 user accounts, put them in to a file, one per line. Then I ran imaptest with
./imaptest userfile=../../imap-test-userlist-15001.txt clients=15001 pass=SECRETPASSWORD
But CPU load is only reaching 20.
I put an mbox containing 67 messages into ~/mail/dovecot-crlf
So what is the best way to put a really heavy load on an imap server? The documentation describes testing correctness of the server without really emphasising performance.
I would like to do something like dnsperf, which adds a linearly increasing load until the server is unable to cope.
This machine has 24G RAM and 8 cores. I'll be grateful for any constructive suggestions.
