I did a lot of tests but can't remember what the result of my tests were. At least I decided not to use separate metadata partition, I think because I didn't have enough disks to really separate the spindles. And one problem was that my tests were not real life tests on a production server. I ended up with a classic setup where /var/lib/imap resides on fast local disks and /var/spool/imap was on SAN.
