I&#x27;m not sure where the hangup is, but I&#x27;ve found that Edge is fast as hell for initial page startup, but lags behind quite a lot when under heavy load.<p>I&#x27;ve seen the benchmarks but in my experience it just... lags...<p>For example, on the kangax ES6 compatibility table [1]. On chrome clicking a column takes less than a second, on Edge (i&#x27;m on an up-to-date Windows 10 machine, no preview stuff) it loads faster than in chrome, but takes 3+ seconds to switch between columns.<p>Even some of the stuff i&#x27;ve written acts similarly, and i can&#x27;t figure out why.<p>[1]<a href="https:&#x2F;&#x2F;kangax.github.io&#x2F;compat-table&#x2F;es6&#x2F;" rel="nofollow">https:&#x2F;&#x2F;kangax.github.io&#x2F;compat-table&#x2F;es6&#x2F;</a>
