Bayes and MySQL ? performance ...

[Phibee Network Operation Center]

Hi

Actually, i have a small lot of SpamAssassin server in 3.2.5
(new install in beta), Each server have a Baye database ...
Do you think's that the best solution are a Mutual Bayes Database
on one MySQL serveur ?

For best performance and HA, what is the best configuration ?
   One MySQL General Server and a local replication on each 
spamassassin server ?

Thanks for your help
