The performance difference between Atom and VS Code is very noticeable on low and mid range PCs. Most of us here on HN are very fortunate that we can afford high end PCs that minimizes performances bottlenecks but we should keep in mind that most of the world isn't so fortunate and that good performance still matters.
I've been developing on a chrome book for the past year. I can confirm that vs code runs very smooth, while atom is finicky and just flat out dies on opening large folders/files.
Kudos to another chromebook dev! Are you running Ubuntu in a Crouton, or another setup? I'm doing that and I run Atom without any complaints. It might just be the way I'm using it however.
I removed the write protection screw, upgraded my ssd, flashed on a new bios from https://mrchromebox.tech/, and installed galliumOS--originally I used chrubuntu, then straight ubunutu. Everything works great. Even installed display link drivers, so I can dock to 2 monitors at work.
Can you open arbitrarily large text files/directories in atom these days? Whenever, I open anything over a few thousand LOC atom seems to lock up for me. I was actually forced to switch from Atom to VSC, because I had a bad habit of accidentally clicking on `node_modules` in the file tree and crashing my session.
I had someone on here mention the write protection screw removal method to me before, I just couldn't bring myself to do it on my Pixel 2. But I should try it, I'm glad to hear someone say it worked out great for them. I definitely want to still be able to boot into the normal Chrome OS because it's preferable to me when I'm not working.
I think I see what you're saying. Maybe it's because the pixel is actually a beast, I don't notice it as much. I have VS Code installed, maybe I should give it another shot. I'm probably just used to Atom, and the only time I really used VSC I was trying to work on one of our really large .NET solutions and it just started throwing hundreds of errors at me. I should try one of my MEAN apps in it.
