I wasn't aware that Pedro was using X on his Mac. The encoding type used
will not affect how long X takes to render things, but will affect how much
data is being passed through the system bus & via main memory, since raw
pixel data is comparatively huge.
What may be Pedro's problem, and the reason that VNC Thing seems faster than
other versions, is that ZRLE takes more CPU to encode - it's therefore the
case that old, slow server platforms can actually be faster if the Viewer is
forced to use Hextile encoding.
