Nothing beats pure hardware for performance. The app will be able to run in CPU L1-L3 cache. With shared cloud hardware there is bound to be cache evictions for the program making it slower. Ie other programs will compete for L1 cache. A fun comparison would be the same program implemented as a monolith on metal vs micro services on the cloud. Why monolith on metal will run in cache and not do rpc network calls. That must be like a hundred times faster. We have global warming programs should be maximum efficient.
