I found some confusing performance data about
the R4 server and OpenWindows 1.0 (XNEWS) on my SPARC-1 (No GX board).

For my own program that draws a lot vectors with "XDrawLines",
OpenWindows is about 3 times faster than the R4 server
to draw the complete picture on the screen.
(measured with a stop watch, not CPU time)

However, for "x11perf -line???" (??? is any legal number),
the results show that R4 server is about 50% faster than the OpenWindows.

Does anyone know why?


Ping-san.
