x11perf is an older test suite, and mostly only tests core graphics. Only x11perf -compwinwin and -comppixwin will make heavy use of pixman (along with the new-style text tests, a*text, aa*text and rgb*text to some extent). The good news is, most modern applications draw using those requests. > 2.xserver use which drawing library to resizing the window,scroll the > text window ,and so on? Depends on the application. Either pixman, or the fb directory of the server. > 3.which library excepts pixman could I optimize using neon to improve > the performance of xserver? xserver/fb But first, make sure you're working on something that matters to your application. In particular, cairo-perf-trace is probably more relevant these days than x11perf.
