What's wrong with an Electron app? I am curious.

They are slow, unoptimised , massive memory and cpu hogs. Here is the best example https://www.theregister.co.uk/2017/03/23/cursor_devours_cpu_...

My opinion is that an advanced text editor or IDE should be written in a low level language to be light weight and fast. Everytime I try atom it performs so bad and slow that I need to switch back to sublime. I even have a probably unfair paranoia bias against editors written in Java because it might be slower than one written in C. Electron has a lot of great uses, but an IDE is antithetical to it's performance capabilities. BTW, I'm in the market for IDE recommendations.

Atom is known to be slow.

That doesn't make all electron-based applications slow.

Atom is slower than VS Code, sure. However, if you end up in a file of any significant size in VS Code, you're pretty much toast.

Good link. Really appreciated.

I would be interested in seeing how that 3GB looked like though.

For instance Emacs has no issues with huge files (logs with many lines), but can completely choke when the lines are really long (like a minified JS-file without lineshifts).

I guess similar constraints may exist in other editors too.

Without knowing how those 3GBs looks, it's hard to make a decent judgement of what the "load" test actually tests.

From the link:

> huge 3 GB file (3M 1K lines)

So, somewhat long lines, but not unreasonably huge.

For me, working on a nasty legacy codebase with 10-15k LOC classes - VS Code is slow enough with syntax highlighting that I pretty much need to use something else.

Actually do you have any prime examples of fast electron apps? I'm interested in finding a DOM-free electron alternative, but if I had a good case study for a legitimately fast electron app, that would be valuable insight for me.

I think VSCode is more than responsive enough. I've had zero performance issues with it on any hardware I own.

The Spotify desktop app also feels millisecond-fast to me, but that might be Chromium Embedded Framework and not "full" Electron? I'm not sure.

You can check out some of my previous comments on my profile. I think we have discussed & covered it extensively here on HN. :)
