I'll give you an example that hammers dev machines like crazy and few wanna talk about it: monorepos. This is now the second time I see performance issues caused by an unruly mess of a monorepo. Add to that single SPAs where multiple frameworks run at the same time and reload on every save and you have yourself a 12-headed dragon breathing fire on your hardware resources. I am not stating this is a monorepo problem, but rather that I have yet to see a monorepo of a large size that doesn't cause this problem.
