How about some details around each of the statistics and how they are calculated or what they are measuring? Also, if you're bored and looking for additional enhancements to make, how about adding a log location where multiple browsers across computers could log their times so that comparisons and load testing could be completed manually? Just a thought, nice work!
Simple, easy, informative. Very useful for quick and dirty benchmarking
fully functionaly for me
A must for any performance engineer!
