Hello everyone,
I tried reproducing the problem and observing differences in speed between
FF2 and FF3 on Windows for repeated RPC calls transferring a String from
client to server using GWT 1.5.3 and did not observe any significant
slowdowns in FF3.

I'll also try this out on a Mac to see if I observe any differences there,
but before I do, is there any reproducible code that some of you may have
that might help reproduce the slowdown on our end?

Cheers,
-Sumit Chandel
