If I pipe the output of ls -lrt to /dev/null, it completes in under a second.

I have a GeForce 9500 GT using the almost latest drivers (260.89).

Running in an xterm:

JJR:/cygdrive/f/download> xterm -version
Cygwin 6.8.99.903(261)

And this X server:

Welcome to the XWin X Server
Vendor: The Cygwin/X Project
Release: 1.9.2.0 (10902000)
