VsCode surprises me to be honest. Besides slow starts, it does not seem to be suffering from any major slowdown for me. I’d expect that thing to get bloated pretty far, really fast.
VS Code does become slower for me on my MacBook M1. I typically don't restart the app unless I have to. After few days of usage, scrolling the code area becomes so slow (<20fps) that I have to restart the app. I haven't experienced such slowdown in other IDEs, such as Xcode or Qt Creator.
I wonder if there are any other native IDEs with the same level of functionality. I feel like electron is forcing me to compromise on performance in exchange for features.
The most important features for me would be responsiveness (I usually have multiple projects open simultaneously, and performance tends to degrade after a few days) and memory consumption.
