VS Code Terminal Sleeps While Pasting

Why is pasting into VSCode Terminal slow? Because it sleeps for 5ms every 50 characters. // Writing large amounts of data can be corrupted for some reason, after looking into this is // appears to be a race condition around writing to the FD which may be based on how powerful the // hardware is. The workaround for this is to space out when large amounts of data is being written // to the terminal. See https://github.com/microsoft/vscode/issues/38137 const WRITE_MAX_CHUNK_SIZE = 50; const WRITE_INTERVAL_MS = 5; export class TerminalProcess extends Disposable implements // Queue the next write this._writeTimeout = setTimeout(() => { this._writeTimeout = undefined; this._startWrite(); }, WRITE_INTERVAL_MS);

A screenshot of a post joking that pasting into the VS Code terminal is slow because the terminal deliberately sleeps for 5 milliseconds every 50 characters. The punchline is that the displayed source code literally shows a 50-character write limit and a 5-millisecond interval, turning a technical workaround into an absurd explanation for the sluggish behavior. It is shared as a reaction by developers complaining about slow terminals or awkward software design.
