Re: Why is JNDI so slow by nature

Distributed Garbage Collection (DGC) can often play a part in these delays by 
creating additional calls to the remote VM to check on liveness of the object. 
If you can, I'd suggest using stack dumps to asses where in the call chain 
things are at when these delays occur.  That should give you a lot more 
information about what is actually going on.
