Hello,
Did you try enabling hw acceleration?
(removing -Dsun.java2d.noddraw=true in their config).
Wouldn't necessarily help, but worth trying.
Another thing to try - turn off the Swing's gray rect fix:
-Dswing.bufferPerWindow=false
Thanks,
Dmitri

A subset of users (myself included) experience extremely bad mousewheel
scrolling performance, but only when running on Java 6. It does not seem to be
affected by specific hardware (I've read reports mentioning both ATI and NVidia
cards). Neither does the presence/absence of Microsoft IntelliPoint make a
difference.
My platform is Windows 2000 running JRE 1.6.0_02, however it seems that the
same (or very a similar) problem manifests on Linux.
DirectDraw pipeline is disabled. Without changing any of the other external
factors, it's very easy to observe the problem by switching between JRE 1.5 and
JRE 1.6.
In some situations, it takes more than 10 seconds (!) of 100% CPU load to
consume all the mousewheel scrolling events.
During these periods, one thread from the JVM process has >90% CPU load
(reported as 50/50 kernel/used by SysInternals ProcessExplorer).
Native stack of this busy thread looks like:

awt.dll+0xe71c1
jvm.dll+0xc06bd

I've searched the Sun Bug Database without any results. Is this a known
problem? What can I do to provide more information?
