That's specifically an example of an application that I think is slow. It's slow to load and often slow to respond. The support for Git has to be amongst the slowest of any professional application in the world. But I'm pretty sure it has a deeply flawed architecture compared to VSCode.

It's written in C++ and .NET Framework. VS is mostly an exception anyway. I much prefer to use VS Code + Rider instead. Your comments leave me with impression that you are not interested in understanding the performance profile of .NET and are looking to engage in a language flamewar instead.

Edit: I stand corrected, based on reply in a sibling comment most of the perception stems from how .NET Framework works. Understandable.
