What are you saying here? It is true that VS Code is less bad in terms of responsiveness in comparison to Atom. Zed, however, is written in Rust (i.e., not Electron), and I would guess it is at least an order of magnitude more responsive than VS Code across every possible scenario.

Web technologies are an unrivaled technological marvel for what they are, but it is disingenuous to imply they represent anything near the peak of what we are capable of in the context of performance.

It depends. It definitely opens faster and the general UI seems a bit faster, but open a largish file (a few MB) and VSCode will easily out-perform Zed because it doesn't have that fancy CDRT thing.

In my experience VSCode is plenty fast. Use it with no extensions and you will have zero problems with performance (though memory use isn't great). The real problems come when you have extensions, especially because it's often impossible to attribute performance issues to them because they can often do a lot of work all in the same "extension host" process.

Why is Zed using a CRDT when I open a source file to edit code? Are they using it for more than their multiplayer stuff? (agentic stuff?)

Based on this comment [0], they're building DeltaDB as a version control system which uses a CRDT, so I assume even in single player mode, the file will instantiate its own CRDT for fine grained tracking of changes.

If you use vscode on a platform with limited resources you will see that vscode is absolutely NOT fastand zed outperforms vscose long way. Extensions or not. And electron is a pleague that needs to pass from this world

> you will have zero problems with performance (though memory use isn't great)

Memory use is a part of performance, though, so I definitely would say VS Code has serious performance issues. It's why I no longer use it, in fact. It's inexcusable for something to eat as much RAM as VS Code does.
