It depends on how many collection-links there are between entities in your db-model. Try to enable hibernate-SQL logging. If you see a lot of eager loading here, you'll be using a lot of mem (and a lot of cpu/network latency).
None of my Apps would run at a near-decent performance *without* lazy loading. If you're getting LazyInitialisationException, try either the session per conversation pattern, or reload all your entities from Ids using a datasqueezer and a custom PropPersistenceStrategy. > -----Original Message----- > From: Chris Chiappone [mailto:[EMAIL PROTECTED] > Sent: Tuesday, January 31, 2006 5:12 PM > To: Tapestry users > Subject: Re: Recommended Memory Req's > > > I am actually not using lazy connections.
