RUM – What and Why
§ Synthetic monitoring doesn’t work
– E.g., keynote, gomez, catchpoint etc.
– Limited coverage
– Single user
§ Real User Monitoring
– Beacon based (Javascript/Boomerang lib)
– Performance metrics from browsers of real users
– E.g., TCP connect time, Page download time

4. 4
RUM – How
§ Navigation timing API
– Most browsers support it
– Browsers record performance timers for each page load
§ JavaScript timers
– For everything else

5. § Browse to www.linkedin.com on Chrome
§ Open “Console” on Chrome Dev Tools
– Mac : Cmd + Opt + J
– Windows/Linux : Ctrl + Shift + J

Connect Time:
rum.connectEnd – rum.connectStart
Download Time:
rum.responseEnd – rum.responseStart
Request to Response time:
rum.responseEnd – rum.requestStart

Higher Network request time means higher TCP timeouts yielding in higher page download load times.
