Server CPU stays on 100% when e-commerce site runs

I have developed an e-commerce website on .NET umbraco. After deploying it i have made a load test with 100 users (loadimapct).When ever more than 30 users tried to access the site,it freezes and CPU usage stays at 100% till the test is over. The site is accessing an indexing engine (Fact-Finder) internally which is deployed on a Tomcat Server. Here is a snap shot of the condition.

Snapshot

I have checked the site with profilers but there is no heavy process running that i can see.

I have made a check with DebugDiag tool (Troubleshooting High CPU in an IIS 7.x Application Pool ).It indicates high CPU usage but I can't understand which page or resource from my website makes this,So i have attached a copy of report. Detail Report Link

can any one Help on this ?

The symptoms you see can be result of various factors.

Trouble shooting and debug these kind of problems the below tools will assist you.

  1. Debug Diag
  2. Performance Monitor (perfmon.exe which comes along with windows)

You can set up debug diag to capture a memory dump when the CPU usage exceeds and use the Automated dump analysis which may help you in identifying the root cause.

For a more detailed step by step explanation you can follow steps in Troubleshooting High CPU in an IIS 7.x Application Pool
