[comp.windows.x] pixrect vs. cfb for Xsun implementations

lalonde@nicmad.UUCP (John Lalonde) (09/06/88)

A while back there was some articles posted that discussed
alternatives for improving the X11R2 server implementation for Suns.
One strategy was to tune the cfb code a much as possible.  Another
strategy mentioned was to rewrite the ddx layer to use pixrect rasterops
instead of the cfb code.

The question is:  Has anyone emperically determined which is the better
strategy in terms of performance? Does anyone have any other comments
concerning this issue? Does anyone know how efficient the basic pixrect
rasterops are compared to tuned cfb code?
Thanks for any comments...

If it would have been easy to use the pixrect code to support the
MIT sample server,  we would have done it.
