I'm a long-time game developer, and plenty smug most of the time about the absurd waste of resources in modern software development. However, aside from the principle of the thing... I use VSCode all day, every day. Most of the time, I'd have no way of telling that it wasn't native. It's fast and responsive. I can't think of anything about it that seems laggy, and that's on a 4 year old laptop. HOWEVER, I have several times seen it get into a state where it's unusably slow. As in, type a character, and it shows up 500 ms later. Now, maybe this is a bug that can be fixed. Or, maybe it's a fundamental problem with trying to make an app that forces you to effectively work in a VM, all the time. Anyway, I still wouldn't have believed, 5 years ago, that a JS/HTML/CSS app in a browser could be so snappy, overall. Maybe it's just a matter of time before perf is great across the board. Or, maybe, like heap-walking GCs, they will always be fundamentally prone to pathological cases, because the whole idea was fundamentally flawed from the start.
