IntelliJ is not very fast by any benchmark. I mean it's based on Swing! There's a pronounced multi-frame pause between right clicking and seeing a context menu.

C++ based editors like Kate blow both VSC and IJ out of the water. Runs so fast it feels janky, like the computer isn't doing anything.

It's from the KDE project, and while it's portable, but I can't speak for how well it looks on other platforms.
