3hrs of Performance test
We are running a performance test with high volume of users (1500+) against a Virtualize installed on a windows server 2008 R2 and we noticed that:
first hour: CPU usage is reaching 40-50% usage
third hour: CPU usage is reaching 90-100% usage
checked the task manager > process and saw that java.exe is taking much of the processor usage
Below are the specs
Intel xeon CPU E5-2698 ( 4 processors), 16gb RAM. we've followed the Document provided by parasoft experts with regards to Performance tuning the virtualize server.
