There's no input delay in VSCode (editor, ui) because the UI is local. Delay in saving/reading/sesrching in files is not noticable for me.
(edit to explain: VSCode is still running locally, but it also installs the server-side (headless) component on the remote machine. That way editing files is local/fast, but stuff like running the code, search/replace/etc also works fadt because it's handled by the serverside).
Terminal (incl vscode terminal) feels slightly sluggish, and it's noticable if the server is in another country and uncomfortable if across the pond.
The input delays are very dependent on where the server is and what it is doing. If the server is idle and close by (ping wise) delay is virtually indistinguishable from local VSCode. If I'm connecting to the server via a VPN in a different country while stressing all the cores with some background compiling or number crunching work, input delay gets quite noticeable.
