Performance in 2012
Performance bottlenecks have moved
from the backend to the frontend
© 2012 Torbit 3

4.
Problem
Limitations of synthetic testing (active monitoring)
Limited visibility
Expensive
Strains the systems you are testing
Limited test locations and browsers
Backbone connections paint an overly optimistic picture
Can be easily gamed by CDNs or other providers

5.
Problem
Website performance is viewed as a
technical metric instead of a business metric

6.
A better idea
Real User Measurement
Use JavaScript to measure every visitor on every page
and correlate how site performance impacts
the business metrics you care about most

What we’ve learned
since launching Torbit Insight

The golden rule of performance
Backend
7%
Frontend
93%
Using TTFB as the marker between frontend/backend

Takeaways
Every second counts
If you want accurate data, use Real User Measurement
It’s important to really dig into your data
One second load times aren’t always a good thing
You need measurement first before you can improve
Nothing beats looking at your own data
