More likely you'll find that in modern JVMs, object creation for short lived objects is essentially free, and JNDI lookups (btw, you're using Seam, right? Where are you directly interacting with JNDI anyway?) aren't going to be significant. Spend some time with a profiler an find out what's going on. It's irrefutable, and will show you where you should spend effort optimizing. You may find that there are performance issues with Seam. You'll also find that if you can clearly show the issue, the Seam team will be extremely responsive in addressing these.
