Please note that this message will contain a full copy of the comment thread, including the initial issue submission, for this request, not just the latest update. Category: None Group: None >Status: Closed >Resolution: Wont Fix Priority: 5 Private: No Submitted By: Pierre Ossman (ossman_) Assigned to: Nobody/Anonymous (nobody) Summary: Full use of SSE registers on x86_64 Initial Comment: The current x86_64 SIMD code is just a straight port of the i386 code. x86_64 has twice as many SSE registers though which means we can increase the parallelism and the performance. ---------------------------------------------------------------------- >Comment By: D.

R. Commander (dcommander) Date: 2011-03-18 13:48 Message: I had a chance to investigate this for the colorspace conversion code (j[c|d]clrss2-64.asm). Quite bizarrely, using additional registers does not appear to improve performance and in fact decreases it for that code. I am at a loss to explain. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=1126849&aid=2814631&group_id=254363 ------------------------------------------------------------------------------ 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-d2d-c2 _______________________________________________ Tigervnc-devel mailing list Tigervnc-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/tigervnc-devel
