[jboss-dev-forums] [Design of JBoss Portal] - Re: portal clustering problem when using optimistic locking

Sounds like activity on the entity cache should be almost entirely reads, which should scale. Doesn't sound like there would even be that many cases of db read + cache write after an initial warmup period.

Is the web session clustered? If so, be sure to use buddy replication for the web session cache or the session replication will inhibit scalability.

Do the use_query_cache=false bit first though so we know whether that has an effect. :-)
