Comment on RUM Charts Side-by-Side With Synthetic Charts by Vik Chaudhary

Vik Chaudhary — Fri, 01 Mar 2013 03:26:54 +0000

Hi Leo, it’s very useful to see a major web property share their RUM and synthetic performance measurement data! The first graph makes a lot of sense – synthetic measurements are usually taken from locations that are very similar (connection speeds, bandwidth), so you’re going to get more consistent page load times. RUM data is generated from locations where the connection speeds and bandwidth differ widely, so the data varies accordingly. I suspect that if you used synthetic DSL agents, OR synthetic agents that are bandwidth-throttled to emulate DSL speeds, you will get different results. In short though, synthetic is good for determining if performance has changed (it’s a clean room lab), and RUM is good for determining exactly what is the performance for a population of users (as long as you can filter down to that population of users, e.g., everybody in Boise with DSL).
