Yeah - I'm running global too. Not per user.
why do you have 7 servers and only one mysql server ? :)
well to get more performance out of mysql one need to use clustered
backends aswell, so to get most performance it would make sense to read
from all mysql servers (read only) but on update (write only) to master
mysql server that will replicate to other mysql servers that can be
readed from, is your servers doing more writes then it reads then its
spamassassin optimizing needed, not backends
mysql is memory hungry btw, here i use mysqltuner with good results, if
mysql is failing change to postgres cluster
