The x11perf is a good analyzing tool, but for server implementators, not for users. Normally you cannot guess the speed of a specific server implementation from this bulk of numbers. Also the x11percompDR is COMPLETLY USELESS, since there the numbers of two test were compared WITHOUT wightening the resuslts. It's obviousely that painting a point is quite unimportant compared to scrolling a 500x500 area. Thus the direct comparishon is misleading and totally wrong. The xbench is much better, cause not all primitives were tested, but those which are *very* important for everydays work. And the results are much more balanced. From the raw number of xstones you can guess how fast your server will be at work. And don't joke with the comparing to a sun 3/50. I think it's quite wise to select a LEVEL 0 for all other tests. Thus you can guess what the number 20000 xstones means if you worked allready with another x-server with a well known rating. - Thomas -- _______________________________________________________________________________ E-Mail (domain): roell@lan.informatik.tu-muenchen.de UUCP (if above fails): roell@tumult.{uucp | informatik.tu-muenchen.de} famous last words: "diskspace - the final frontier..."
