JDK 1.5 is slow in some machines ???

[hp]

Sometime before we have moved our RMI Client-Server Application from
JDK 1.4 to JDK 1.5(Tiger).
We have noticed great improvement in Application Startup Time and
Speed.
But with two of our clients, Application Startup Time is
poor(extremely slow).
The VM arguments and other settings regarding our application is same.

What could be the reason for slowdown? something to do with display
or Network
or VM arguments or ... We are not sure.

Can anyone help me with some suggestion?

A possible culprit are over-eager virus scanners that insist of scanning the
entire contents of ZIP archives when they're opened. The Java class libraries
are in a very *big* JAR (same format as ZIP) archive.
