A walk through the Skylight UI

Response Time

There are several places that your application's response times appear in Skylight. It is important to note that we always show the 95th percentile response time, not the average. While this take significantly more computation on the backend to determine, it is a much, much better number to indicate real world performance than the average.

Averages are almost useless when thinking about web performance, and in the worst case, are actually misleading. For more information, see DHH's blog post The problem with averages. Google, Twitter, and GitHub (to name a few) all use 95th percentile numbers when tracking performance.
