A DESCRIPTION OF THE PROBLEM :
I have one class repository in my network with about 30,000 classes, all in same package. This repository is used as a network mapped drive in all developers machines. The network works at 100mbps. Everything works fine until now, when I am testing java 6. Currently we are using javac 1.4, and compilation takes about 20 seconds. But with javac 6.0, its taking about 2 minutes.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
One package with about 30,000 classes in some network mapped drive.
Put this network mapped drive in classpath.
Compile one class that depends from some of that classes.

ACTUAL -
Compilation takes about 2 minutes in javac 6.0
