I compare to graphs: "Response Times Over Time" and "PerfMon Metrics Collector" with CPU Metric. I noticed that sometimes response time is significantly increased and it looks like it happens when cpu load is 100%. Can i say that performance problem is caused by weak CPU here?

Re: Result interpretation
multiple parameter responsible for high response time, you need to use perfmon counter based on server.
