Here's a way to do it in Linux:
1. Fill up the mailbox with messages:
imaptest logout=0 - append=100,50 msgs=10000 user=testaccount
When it finishes, imaptest goes to infinite loop and you have to kill -9 it. I guess I should fix that some day.
2. Flush page cache: echo 1 > /proc/sys/vm/drop_caches
3. time doveadm search mailbox inbox text asdfasd
After 3 the mailbox should be cached, so you can run it again. Get imaptest from http://imapwiki.org/ImapTest
In non-Linux step 2 can be achieved by rebooting. :)
