Oh, let's see...
(1) Do you have 10 databases or 10 database servers? I'm a bit
unclear based on your description?
(2) The limit of 100 clients per server is default which can be
changed. Some folks have had many, many more than that on a
reasonably configured server.
You can use MySQL replication to do some load balancing. You can have
a master database server (db0) and then configured db[1-9] as slaves
which get all their updates from db0. Then code your software to send
all updates to db0 and the bulk of your read-only queries to one of
the slaves. Which slave? It's up to you.
Does that help a bit?
