Hi Jordan, Looks like we made a little more progress on graphics benchmarking. See Neil's results below.
I updated the feature page with the test results so far: http://wiki.laptop.org/go/Feature_roadmap/General_UI_sluggishness What's next? Do we know enough now to target a particular section of the code for optimization?

Done. http://screamingduck.com/Cruft/cairo_benchmark_XO_NoAccel.txt At a cursory glance it looks like an overall improvement without acceleration except for lines-xlib, add-xlib and over-xlib _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
