1350 ms, that is to say 1.3 seconds? Depends on your hardware and
network of course, but these days RMI "null calls" (no work done in the
server, no args, and a void return) are generally less than millisecond.
Do you know how many bytes are in the return value? The other side of
this is how much time is each call spending in the server?

When an object appears more than once in a serialization stream 2nd and
subsequent appearances are replace by a 5 byte (I think its 5 bytes -
something on that order) "pointer" to the first appearance. This can
result in quite a bit fewer bytes being sent. If the 500 record case was
really 5 copies of the 100 record case it might end up being reprsented
by a similar number of bytes because of this.

Hope this helps
