xscreensaver manipulates the gamma setting for the screen (equivalent of 
calling xgamma in a loop with successively smaller gamma values), which 
allows for a smooth fade of the entire screen. This isn't really 
possible if you want to fade part of the screen but keep one dialog at 
full intensity (the logout dialog).

So it isn't that surprising that xscreensaver can do the fade faster, 
since it is doing something different.
