The only thing that comes to mind so far is that ejb cmp 2.1 entity

There were some reports early on that in some situations this was a
lot slower, but I think that in other situations it was faster. Are
you using cmp 2.1 entity beans?
That seems like a pretty good hypothesis.
Andrew,
Have you monitored memory utilization? I'd turn on verbosegc. Possible
that you're getting into a memory constrained situation and spending a
lot of time GC'ing (but never running out of heap)
Barring the above, I'd suggest you profile your server. Or, if you
have a test application that can illustrate this issue, we'd be able
to find somebody that could take a closer look.
