On my Apple M1 it takes ~33 seconds for cold-start. I use only vim and flutter extention. That said, my biggest complaint is that on this extremely fast computer, the lag between a keypress and a symbol is too big. I'm typing faster than VSCode renders characters. With vim mode enabled it sometimes goes super slow, with 1-2 sec between characters (but that's not always).

Anyway, agree with the author. Everytime I use web- or electron-app I'm just expecting sluggishness, ugliness and weird behaviors and refresh the page (=restart the app) all the time. It's just a norm. I guess no matter how people pretend that typesetting engine from 80-s is a good UI stack, they still have to pay huge price in usability, performance and orders of magnitude higher memory usage.

How is this possible? What is a "cold start"?

For me, with Code completely exited (i.e., not in the dock at all), it takes about 1 second to start drawing and about 4 or 5 to finish rendering all the icons and such and be fully usable. Even IntelliJ (now THAT's slow) only takes about 6 or 7 seconds to fully load. On a M1 too.

Do you have some weird antivirus or similar scanning all your apps...?

By cold start I mean, I haven't launched the app in the last days, so it's not in any sort of cache or memory pages.

No, I don't have any antivirus, and generally very concerned about what's running in the background (I delete apps from LaunchAgents dir, avoid keeping hungry Electron apps in the background unless really needed, etc).

I don't understand how it's so slow for you then. I don't even use VSCode regularly (prefer the other IDE), but I keep it around specifically because it's so fast to open. A good lightweight alternative when I don't want to wait for my real IDE.

It's never taken more than a few seconds to load... whether on M1 or x86 Macs or Windows. How weird.

I don't know either, but it's definitely a common case. They have around 200 issues devoted to startup performance.

Meanwhile, NeoVim is consistently starting under 500ms for me, even being heavy loaded with plugins and offering all the same functionality (NeoVim is pretty awesome as an IDE these days).
