Software is slow because of bad design, not slow languages

Had the same experience when I was testing zed. Was thinking it would be a lot better since it's written in rust but there wasn't any difference in memory/CPU usage between it and VSCodium, which is electron app.
Even nvim will eat up about 5GB of RAM when used as an IDE. MCP alone will use that much of RAM independent of the editor.
From what I remember, Vscode has quite a fair bit of native code in various areas to make it perform better. So it may not be the representative Electron app for comparison.
Electron is also the worst web based toolkit out there. Solutions that use system webviews instead of running whole Chrome are much lighter.
