The X Server renders perfectly well and my favorite applications do start up and run. However performance is extremely slow -- it is slightly too slow to be usable. For instance I tried some graphical text editors, and a [PageDown] press take 0.25 seconds to render: Whereas on a commercial X Server running side-by-side on the same Windows desktop renders in <0.03 seconds. I am a bit confused if this is intended this way: i.e. is this just a demonstration of the capabilities of CygWin, or is it actually being used by anyone? I ask because there are no reports of anyone finding the X Server slow, yet the software has been many years in release.
