Until you install the enough addons to VSCode to give it the same functionality JetBrains products have out of the box, then it gets slower.

JetBrains' IDEs are very heavyweight, it's apples to oranges. And while there is some native code in them, they're still driven by the JVM mostly. There is fleet, but it's not an improvement to vscode at all IMO.

How about vscode vs sublime, neovim, or any other native text editor with LSP support? vscode is slow comparatively.

VS Code is primarily an editor, while JetBrains's products are IDEs. You can add extensions to make VS Code more an IDE. And I'd like to see benchmarks proving your point. If you're using VS Code as an editor, others like Sublime Text, Notepad++, Kate and TextMate make it seem very slow.

In fairness, the core of VS Code is really well-crafted highly performant code. It was designed to be fast and to work for a web integrated code editor from the start. After trying Atom and Brackets, I almost didn't touch VS Code when it came out, I'm glad I did decide to try it as I really do like it.

Of course most Electron apps don't have near the same level of effort or foresight when it comes to performance. Discord probably the second most common electron app, and Teams being third. Both of which, at the very least, have issues. Some could be overcome, or at least be more consistent with WASM built controllers, but that whole space needs some maturing and improved tooling. I've played with Tauri and Yew and think it's pretty nifty, but there's a lot of work to getting parity with say React+MUI.

React+MUI itself is pretty good. But even then, on a relatively large team with some relatively inexperienced devs, you can wind up with dependency trees that are insane, huge and slow. Taking that and going through the extra hurdles that the likes of Electron, Tauri or others add is burdonsome to say the least. It can be very nice, but usually isn't.

And while I empathize with the teams using Electron, I can even support the ideas. In the end, it's the outcome that matters. I'm not one of the never-electron types. But I also recognize the issues. I use Tabby for my terminal, which is fast enough, but still takes 3-4 seconds to load. I use VS Code which is usually a couple seconds as well. It drops off dramatically from there.

There are massive advantages a browser renderer offers... it gets all taken away by importing whatever library comes up in your npm search for any given thing.

That's damning with faint praise, though, isn't it?

There is simply no comparison between the two. Its like comparing MS Notepad with MS Visual Studio. Jetbrains IDEs are so much ahead of even Visual Studio.
