VSC is not the exception that proves the rule. VSC is the counterexample that disproves the rule.

Slow electron apps come from a culture of not caring about performance. It's not a technical problem but a values problem. C++ developers _tend_ to care more about resource usage. Any GUI will be slow if the developers stop caring about repaints, even one written in C++.

C++ GUIs are fast because people sit in front of profilers and make them fast. Not because C++ is a magical language where every operation takes less than 16ms. Chromium has great profiling tools available. The chromium team has put a lot of effort into making performance tools available and then people ignore them and say that it sucks.
