ISA Firewall Service Process (wspsrv.exe) high CPU utilization issuehttp://blogs.technet.com/b/isablog/archive/2011/01/26/isa-firewall-service-process-wspsrv-exe-high-cpu-utilization-issue.aspx1. Introduction &#160; When dealing with ISA high CPU utilization where wspsrve.exe is the one consuming more resources, the first impression is that ISA is the culprit for that. There are some scenarios where this statement is true, such as this oneen-USTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)re: ISA Firewall Service Process (wspsrv.exe) high CPU utilization issuehttp://blogs.technet.com/b/isablog/archive/2011/01/26/isa-firewall-service-process-wspsrv-exe-high-cpu-utilization-issue.aspx#3382820Thu, 27 Jan 2011 01:27:25 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3382820Yuri Diogenes [MSFT]<p>I understand your point, however in not always that we have a wait condition CPU will be zero, it depends how the process that is consuming CPU works in order to perform other actions (allocating new resources) while other threads are waiting for other things to happen. </p> <div style="clear:both;"></div><img src="http://blogs.technet.com/aggbug.aspx?PostID=3382820" width="1" height="1">re: ISA Firewall Service Process (wspsrv.exe) high CPU utilization issuehttp://blogs.technet.com/b/isablog/archive/2011/01/26/isa-firewall-service-process-wspsrv-exe-high-cpu-utilization-issue.aspx#3382819Thu, 27 Jan 2011 01:27:11 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3382819Yuri Diogenes [MSFT]<p>I understand your point, however in not always that we have a wait condition CPU will be zero, it depends how the process that is consuming CPU works in order to perform other actions (allocating new resources) while other threads are waiting for other things to happen. </p> <div style="clear:both;"></div><img src="http://blogs.technet.com/aggbug.aspx?PostID=3382819" width="1" height="1">re: ISA Firewall Service Process (wspsrv.exe) high CPU utilization issuehttp://blogs.technet.com/b/isablog/archive/2011/01/26/isa-firewall-service-process-wspsrv-exe-high-cpu-utilization-issue.aspx#3382749Wed, 26 Jan 2011 20:09:15 GMTd5e57398-b9ef-4490-9955-07cbb4e4a80d:3382749Dmitry Mashkov<p>If this was a wait, why does CPU utilization is so high?
