X11PERF12, MOTIF TOYS, X11 server performance test program The x11perf program runs one or more performance tests and reports timings of the operations. Many graphics benchmarks assume that the graphics device is used to display the output of a single fancy graphics application, and that the user gets his work done on some other device, like a terminal. Such benchmarks usually measure drawing speed for lines, polygons, text, etc. Since workstations are not used as standalone graphics engines, but as super-terminals, x11perf measures window management performance as well as traditional graphics performace. x11perf includes benchmarks for the time it takes to create and map windows (as when you start up an application); to map a pre-existing set of windows onto the screen (as when you deiconify an application or pop up a menu); and to rearrange windows (as when you slosh windows to and fro trying to find the one you want).
