I believe Android Studio is built on top of IntelliJ IDE which uses Java, so no Electron. That being said, Java applications are generally RAM heavy as well and Android Studio was always a pig on resources.

Visual Studio Code (not Visual Studio!) is Electron based but I've always had good performance with it.

Visual Studio Code

Yeah, that's one that I can't talk badly about.
While I have used MS Visual Studio and know how slow it was, I tried VS Codium once or twice and it worked pretty smoothly. Someone probably put quite a bit of effort into making it so.

Apart from Android Studio, which ended up not even starting up properly on the work computer, Gradle itself also takes quite a bit of time and resources. I was using the NDK with a C++ project and it took way longer to setup than any BSP, despite only being able to compile for a single version of Android.
