NAME
Xmark - summarize x11perf results SYNTAX
Xmark datafile DESCRIPTION
Xmark is a shell script that reads the indicated datafile and compiles a benchmark which it writes to standard output. It writes three numbers: A weighted performance number for the x11perf results. A weighted performance number for a standard SparcStation 1, with SunOS 4.1.2, X11R5 Xsun, and a CG3 dumb Color Frame Buffer. The Xmark, which is the ratio of the two numbers above. The datafile must be an ordinary file, produced by x11perf in the following way: x11perf -display display -v1.3 -rop GXcopy GXxor -all > datafile It is possible to run the GXcopy and GXxor tests separately, as long as they are concatenated to the same output file: x11perf -display display -v1.3 -rop GXcopy -all > datafile x11perf -display display -v1.3 -rop GXxor -all >> datafile or x11perf -display display -v1.3 -rop GXxor -all > datafile x11perf -display display -v1.3 -rop GXcopy -all >> datafile FILES
