It appears that the timing functions may be platform related.

I have an internal web site and the access times reported for the same transactions appear vastly different. For example, my Windows 7 (latest Chrome) shows total response times as 200ms (almost 190ms of receiving) while my Ubuntu laptop shows a total of 4ms on the Chrome Network tab.

I also put timers on my server side first, just to make sure that it was not a delay in my node.js server (running on a different ubuntu box - not the one that has the Chrome client).
