The funny thing is that the reason I and many other people switched to VSCode is that it used to be so speedy.
I sometimes wonder how much of its decrease in speed over the last few years is due to feature bloat (which it seems to have in spades) and relying on hobbyists, who have less incentive to optimize, to fill out the plug-in ecosystem.
I moved my personal projects to Nova, and it's screamingly fast. But I still have to use VS for work, and even though I only have four plug-ins, the difference is like pouring water, versus pouring honey.
