I'm slowly migrating some code from EHCache to JBossCache. Until I'm done, will there be any big performance issues with having both TreeCache and EHCache running at the same time? (EHCache will just be used for Hibernate.)
Also, for Hibernate, if I don't need a transactional cache can I just leave out TransactionManagerLookupClass and set IsolationLevel to NONE safely?
Thanks. (So far getting JBossCache to run cleanly in Tomcat has been pretty smooth; if everything is this nice, I may push to migrate our app to JBoss.)
