We use APDEX in order to score our performance tests and take and index. Simply, it counts how many requests are being served under some thresholds. It is quite nice since you can produce an index between 0 and 1 (0: all requests were bad / 1: all requests were good) that everybody, including end users, can understand.

Some browser tools, and the jmeter recorder don't usually pick up ...
