I'd have to say that I haven't done any controlled tests, but mysql can be
very slow when you are doing a lot of connections (correct me if I'm wrong,
but I think it executes requests in order?).

To be untechnical about it and only speak from experience (if I was a
typical internet user, I'd think that because it does it for me, it must do
it for everyone! :) ), I personally have never found sessions to be slow
getting a lot of data, where as I have found it slow with mysql...  probably
also depends greatly on your server load.  I'd imagine that you would see a
massive difference on a server that is under load.
