What is the primary goal of collecting those measurements? Let's assume that the measurements show that Squid adds X% to the median response time in a particular test scenario. Now what? * If the primary goal is to just record/report _some_ number and forget about it, then you can use curl, wget, or ab to generate dumb test traffic and measure overall response times of primary configurations. This (mostly pointless from a purely technical point of view) exercise should not take more than a few hours. It is useful, for example, in cases where one needs to report some measurements to the management, but everybody just wants to mark some checkbox on some list. * If the primary goal is to verify some performance guarantees or tune Squid performance, then you would need to invest a lot more into these performance tests. You need stable, reproducible results and representative traffic pattern(s). I use Web Polygraph (http://www.web-polygraph.org) for such tests, but it has a steep learning curve, may need some love to compile in your environment, and it is a biased recommendation.
