What you see is expected simply because in the local case an entire Code.exe needs to be launched which is a lot more compared to in remote where we just load a small script.

In order to address this we would have to ship a CLI tool that can do opening of files instantly without having to start Code.exe first.

I think the problem is not really running Code.exe is too slow, if I type other commands like code --version, it's not that slow never mind, code cli will redirect open file to Code.exe

This is more of a performance enhancement request than a feature request to be honest...

If I understand correctly, we run a single instance of vscode at a time, all subsequent instances will send the information to the first instance, let the first instance handle it and terminates itself, in that case is it possible we make that part of the code run even earlier so that we don't waste time on initializing other things?

This is something quite annoying when I want to use vscode to open a file from file explorer, I need to wait a bit for it to open and it's even slower than using PowerToys's Peek which is also vscode (monoco editor)...

We can eventually make the Rust CLI the primary entrypoint, though for this particular case we'd have to share contract with the CLI so that it can do the appropriate messaging to make the open file request.
