A cairo trace (http://cgit.freedesktop.org/cairo-traces) for this website is interesting even if recorded on a linux desktop system instead of your android device. Just because this use case also shows a clear performance problem as can be seen by profiling. Having a cairo trace, we can optimize pixman code and get easily reproducible benchmark numbers by replaying this trace before and after optimizations to verify how good are the results (and whether they are good at all). Unfortunately, all that I could record so far is a broken trace :-( Maybe somebody else will be more lucky? If anybody is interested, just go to http://manichord.com/opensign/ffdebug/ffscroll.html in Firefox, press ctrl-+ to zoom the page a bit and scroll it left/right for a while. The Firefox browser needs to be launched by the cairo-trace tool. -- Best regards, Siarhei Siamashka _______________________________________________ Pixman mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/pixman
