Measuring Web Performance

A session at Velocity Europe 2011

Tuesday 8th November, 2011

2:40pm to 3:25pm (CET)

How do you measure web page performance?

We all talk a lot about how fast our web pages are but are we comparing apples with apples?

There are at least 6 different ways to measure web page performance, and multiple metrics to gather such as initial render, “above the fold” time or onLoad event time.

The goal of this talk is to put web performance measurement in perspective by identifying and classifying the different ways of measuring web performance.

So what dimensions can we compare them on?

1. Accuracy?
2. What metrics do they collect?
3. “Completeness” of measurement – e.g. can they measure 3rd party or CDN content?
4. Ease of implementation / use?
5. Scalability (e.g. are they suitable for “real-user monitoring” type solutions or are they more developer/single-user oriented?)
6. Are they suitable for Mobile devices?
7. Are they suitable for measuring web API’s?
8. What’s the cost?
9. Suitable for SME vs Enterprise?

We will also talk about the “active monitoring versus real-user monitoring” debate… what are the pro’s & con’s of each approach and will one eventually supplant the other?
