Inline JavaScript Experiment

[calumfodder]

The results seem to show that in the experiment you are testing on WebPagetest that the external resource is taking a shorter time than the inlined resource, so it might be possible to surmise that the costs of inlining are outweighing the costs of an external extra resource, and are not in line with what you believe (if I have correctly understood your position). This is going by the First view Load time metric as the other metrics are so similar, TTFB only has a spread of 31 ms for the repeat view and 56 ms for the first view with no apparent separation between the result groups for A and B. The First View Load Time only has a spread of 159ms with a separation between the results groups of 73 ms (between highest result for A and lowest result for B).

What is the most important metric that you want to improve with the experiment?
