Hi, Which arch did you run those tests? There have been some discussion on some perf issues on ARM for stuff that is new on 1.9.2. Can you run the test under cairo-trace so others can reproduce your benchmark? See <a href="http://cairographics.org/FAQ/#profiling">http://cairographics.org/FAQ/#profiling</a> Rodrigo <div class="gmail_quote">On Wed, Jun 17, 2009 at 7:52 PM, cu <<a href="mailto:cairouser@yahoo.com">cairouser@yahoo.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Good day all! 狢 decided to test our application (that currently uses Cairo 1.8.6) with 1.9.2 snapshot. A quick test had shown that there is an enormous performance degradation when using 1.9.2. Here are the self-test printout: Using 1.9.2 (times in seconds): Loading running time: 1.11 Transforming running time: 0.06 Drawing running time: 5.18 Using 1.8.6: Loading running time: 1.12 Transforming running time: 0.06 Drawing running time: 0.50 As you can see, drawing time for the same set of sample data increased x10 (5.18 sec vs. 0.5 sec). The application is using image backend and draws approximately equal mix of lines, polygons, "icons" (copies pieces of another image into the working surface) and text output (essentially short labels). This test was performed with Pixman 0.14 and 0.15.12 - there seems to be no difference based on Pixman version. I realize that 1.9.2 is not a release yet - but 10 times loss of performance is something that is not easily overcome. (Personally, I was hoping for performance improvement - we can use a few milliseconds, but now I'd just like to keep what was there before). Any advice and ideas would be appreciated! _______________________________________________ cairo mailing list <a href="mailto:cairo@cairographics.org">cairo@cairographics.org</a> <a href="http://lists.cairographics.org/mailman/listinfo/cairo" target="_blank">http://lists.cairographics.org/mailman/listinfo/cairo</a> </blockquote></div>
