I just came across this free tool for evaluating page speed for WordPress sites:
One of the interesting things this site revealed about one of the sites I tested is this:
Reduce the impact of third-party code
Third-party code blocked the main thread for 380 ms
Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading.
Notice anything about this table?
That's right. They are all Google. The same Google that keeps pushing us to reduce page load speeds.
