From my experience with Firefox (which is better) and Chrome (which is faster, especially on old CPUs, compared to Firefox after installing a similar set of extensions) and the knowledge of Edge being a customized Chromium build (notably with some awesome features added, e.g. a vertical tabs bar) I once speculated Edge probably is fast, also modern-standard, so in many cases there probably is no rational reason to install another web browser on a Windows machine which has Edge anyway. I then found out I was wrong: Egde turnt out to be slower than Firefox, let alone Chrome. All my slower/faster ratings are subjective though, I didn't run any benchmarks, it just really feels slow. Curious to mention that even on a low-RAM (4GB) PC Chrome feels the fastest even though it consumes more RAM than Firefox does.

Cynical take but… maybe excessive telemetry is causing it to chug? Especially if it somehow is waiting for a telemetry server response on a critical path rather than sending async?
