> HotSpot, under a typical configuration, eats up about 250MB just sitting there doing nothing. This is much lower in newer jdk's [0]. > For a slightly more apples-to-apples comparison that's also quite a bit more apples-to-jicama, if I open vscode and IDEA on the same project (a small one I'm just getting started on), vscode and all its helpers are using 316MB, and IDEA is using 1.08GB I believe this to just be intellij bloat and not JVM because it just does too much. I run VSCode with the Java plugins and ZGC (read: eclipse language server, which is all jvm) and the language server only ends up using around 250mb of ram.

I that you're right that it's just IntelliJ doing too much. Similar to how the Slack app's formerly astonishing memory consumption was because it was trying to retain all of Giphy in memory for all time. Somewhat related, back when I was a C# developer, I spent a long time being confused over the community's somewhat polar opinions on whether Visual Studio is slow and bloated, or lean and snappy. Eventually I realized that the difference of opinions was because some people's employers buy them copies of ReSharper, and others don't.

  IntelliJ has more features than even the best language service I’ve used, C#’s. The language server tools are catching up but for integration and polish you still can’t beat JetBrains.

  On the subject of the (lack of) snappiness in Visual Studio + ReSharper, Jetbrains Rider comes with the ReSharper functionality built in and feels a lot snappier.

    Rider is incredible. We lobbied for it at work a couple year ago and it's been so darn nice to use.
