The akonadictl fsck/vacuum is certainly faster, its not just a feeling.  I've got a few logins on this machine and so far i've only converted one to postgresl and the mysql ones are still very slow during these operations.  Sometimes with the mysql ones, i can go away and make a cup of tea waiting for them to finish.

kmail does seem a little faster but not so much that its a massive difference except if you get a "retrieving folders..." delay, you can wait ages for the mysql to respond and return to a functioning kmail but so far when i've had this message (only a couple of times since converting) with postgresl, it comes back in just a few seconds.
