My dev machine is sufficiently beefy (32G of RAM). I recently tried https://lapce.dev/ and was very surprised that it was noticeably more snappy than VSC. (I am not super sensitive to that kind of thing after years spent in Eclipse/IDEA.).
Made me realize how I can just become accustomed to a certain amount of lagging....
I recently tried lapce on my Mac and just empty editor with just one new tab was eating 70% of my CPU. I'd better IDE eat 1-2GB of ram than eat my CPU cycles. Also on their github lapce has more than 50% of open issues labeled as C-Bug - that's not very reassuring
