I am not bashing on Electron, but I have seen slowdowns and memory hogging on VS in large projects (Typescript). I end up restarting it every 3-4 hours to get it back a baseline speed.
You’re not at all alone, working across several teams of devs and infra engineers people are always whinging about electron apps that eat up resources, kill their batteries and slow down over time, slack and VSCode are prime examples.
