Asynchronous code doesn’t make something fast. It just prevents the application hanging when waiting for a function to return. But if that function is user facing (eg values for a context menu) and is slow, then your application is still going to feel slow in spite of those functions be asynchronous.

Coincidentally this is actually a problem I faced when writing my alternative shell.

Right, I just meant it wouldn’t hang the UI (as the parent comment seemed to imply).

That wasn’t what I was implying.

I was just saying that you can make the text editor as lightning fast as you want but the moment you need to do anything useful with an IDE you become dependent on the performance of your plugins.

This is why I’m a little jaded when people talk about IDE performance. Unless that IDE is using its own bespoke plugins, and the trend these days is (thankfully) moving away from that, it’s really not a good benchmark any longer.
