Examples include spatial locality and memory latency.

If the ethernet receive completions are being processed and indicated to the protocol stack on targeted processors, it might make sense for the application to assign affinity to the same processor a connection's ethernet receive completions are being processed on.</P> <P>---&nbsp;</P> <P>This is not supported on Windows7 and before, but it is being considered&nbsp;for future Windows releases.</P><div style="clear:both;"></div><img src="http://blogs.technet.com/aggbug.aspx?PostID=3163577" width="1" height="1">http://blogs.technet.com/b/winserverperformance/archive/2008/09/13/getting-system-topology-information-on-windows.aspx#3123304Sat, 13 Sep 2008 11:00:42 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3123304Getting system topology information on Windows; build scalable multi-processor and NUMA<p>PingBack from <a rel="nofollow" target="_new" href="http://www.ditii.com/2008/09/13/getting-system-topology-information-on-windows-build-scalable-multi-processor-and-numa/">http://www.ditii.com/2008/09/13/getting-system-topology-information-on-windows-build-scalable-multi-processor-and-numa/</a></p> <img src="http://blogs.technet.com/aggbug.aspx?PostID=3123304" width="1" height="1">
