Why would you need to optimize the config? I'm not talking about running an interactive shell.

You commented on someone mentioning bash being slow to start.

So your parent discussed interactive shell, and I assumed you did, since you didn't state otherwise.

They were quoting the article, which complains that "shells are too slow to start", with examples of running echo in non-interactive shells.

Nobody is talking about the startup time of interactive shells.
