the Performance tab at Google Chrome Developer Tools

Click F12 to open Google Chrome Developer Tools in Google Chrome and then go to the Performance tab. Click the record button at the upper left and you will be able to record a snapshot of the web traffic and JavaScript interactions and memory leaks until you stop recording. The span of time you recorded will present itself to you in a timeline once you've stopped recording and there are all sorts of esoteric things to drill into on the timeline in the name of understanding lag.
