Although it might sound strange I do not believe in low level tools such as
OptimzeIt on EJB level - first stage. Usually you end up using a component
based framework which might be distributed and EJB overhead just changes
results significantly. We switched to a simple set of classes which
NT offers a near infinate number of causes for slowness.
Start by installing a good defrag'er and defrag all disks.
Your new box may have dog slow disks? Eh?

I've had similar symptoms with ATG Dynamo. It usually occurs when the VM
decides to garbage collect. The way we get around this is to have
multiple Dynamo instances each with it's own dedicated VM and CPU. This
makes the user experience more acceptable across all sessions on the
system since
There should be one for each active request.

Hi,
This mail is useful only if you're using entity EJBs.
Because EJB is RMI on steroids (is more than that, but let's keep it
simple), if you need more that one entity to get the data you need for

with the overhead it implies.
