Do I have a performance problem?

I am using cygwin-xfree to access a Linux PC running RedHat 9
from another PC running Windows 2000 Professional over a local
100Mb LAN.

The result is rather sluggish, it takes about a second to "paint"
each remotely displayed window.

I have also had Exceed installed on the W2K PC, and it paints
much faster (it causes other problems, so I don't want to use it).
That proves IMHO that it is not network induced slowness.

The W2K PC is a Iwill KA266-R 850MHz Athlon, 512MB PC1600 DDR,
ATI 8500DV AGP.

Should the display speed be higher? What tuning possibilities are
there?

Xdpyinfo follows below. If any other info can help, I'd be happy
to post it.

Thanks, Willem Riede.
