So I linked Evas against BuGLe, as opposed to plain OpenGL. Initial results of Rect Blend (70) and Image Blend Occlude 3 Very Many (87), run on an Atom N270 and Intel 945GME, can be found here: http://jkukunas.phpnet.us/evas_bugle_runs.tar.bz2 Just as a warning, the log files are large. You can skip all the details and get to the frame-by-frame summaries by searching for "calls per frame" and "average time per call" One thing that immediately catches my eye is that for 87, we're calling glXGetCurrentContext almost three thousand times a frame, at around 0.018 ms a call, depending on which frame you look at... > > -- > ------------- Codito, ergo sum - "I code, therefore I am" -------------- > The Rasterman (Carsten Haitzler) ras...@rasterman.com -- Jim Kukunas Intel Open Source Technology Center ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable. Why? It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense. And common sense. http://p.sf.net/sfu/splunk-d2dcopy2 _______________________________________________ enlightenment-devel mailing list enlightenment-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/enlightenment-devel
