Idea: Extra Analytics Information
This post is more than 18 months old. Since technology changes too rapidly, this content may be out of date (but
that's not always the case). Please remember to verify any technical or programming information with the current
release.
When browsing the documentation for chrome, I came across this:
window.performance.getEntries();
This gives a dump of all the connection and timing information available to the Javascript Timing and Resource API.
Why this is an idea? There could be a service which is just a tiny javascript library inserted on the page that tracks and records this information for each visitor. Additional information can be correlated with it then.
So, why is this useful?
-
You can now tell how many people have an empty cache vs a full cache.
-
When do most DNS queries take longer / does google CDN help
-
Do logged in users have a warmer cache, faster load time, than non logged in users.
I think there is tremendous information to be gathered basically from remote visitor’s network tab. Pretty sweet.
