Hi! While I'm currently looking how to improve the mappaint performance, Ive added a new boolean "Einstein option": mappaint.profiler (default: false).
If you set this option to true, each mappaint repaint will put on the console the time to draw and the number of elements, this will look like: Mappaint Profiler Prepare : 16ms Relations: 0ms, n=97 Areas : 78ms, n=563 Ways : 172ms, n=10945 Selected : 0ms, n=0 Nodes : 109ms, n=21033 All : 375ms This already helped me to identify some performance bottlenecks, and I guess this can help users to quantify their experience e.g. while discussing on the ML. I'm currently looking how to improve the performance (without rewriting/redesigning lot's of stuff) and already found some interesting things, more on that later ... Regards, ULFL P.S: I've tried the JAVA Profiler jrat first, but wasn't really satisfied with the output, so I've "hardcoded" this into JOSMs visitAll() method. _______________________________________________ josm-dev mailing list [email protected] http://lists.openstreetmap.org/listinfo/josm-dev
