For doing analysis on performance, it might be desirable to provide some performance statistics information to developers. The basic idea is based on siarhei's slow-path-reporter. I extended it to accumulate information of every composite paths. Final result will be shown at the end of the application when destructor is called. Each paths are sorted by the amount of time they spent. The main purpose of this utility is to profile cairo traces. We can easily figure out hot spots and real world usage patterns. You can see it from here.     <a href="http://cgit.freedesktop.org/%7Epodain/pixman/?h=perf_stat">http://cgit.freedesktop.org/~podain/pixman/?h=perf_stat</a> You can give --enable-perf-stat option to configure script to enable the performance statistics analyzer. (I'm not sure that this is done right, because I'm not familiar with autoconf, but it works anyway) Is it right or good to include this feature within upstream? I think other developers can easily profile their applications and report the statistics when they suffer from performance. I was thinking of some performance log channel, individual composite event is printed though that log channel and statistics analysis utilities to retrieve meaningful information from the log. All suggestions and comments are welcome. -- Best Regards, Taekyun Kim </body> </html>
