"Response time" by itself is a meaningless performance metric. Useful metrics are the following:
1). Average response time 2). N-th percentile response time (typically, 95% is used; in some high-reliability real-time systems I worked with, 99.9% was looked at). Keep in mind that the response time measurements will be a function of the *system* load - your target server(s), network, load generator(s). This requires a "reference architecture" and a "reference load" be clearly specified with the (usual) disclaimer that the performance is relevant only for that setup. Your lab should also be isolated from the outside; otherwise, you have no control over the LAN traffic and you may see some interesting behavior that could include unrepeatable results, measurements that are a function of the time of day, etc. I would also look at the autocorrelation in the response time samples that are obtained to see whether there are any "hidden" operations occurring. For example, I troubleshot a test environment a while back where autocorrelation showed that exactly every 15 seconds a delay spike occurred - I traced this to reverse DNS queries failing in the lab.

And if you don't mind could tell me how I add the plugins.
