Yeah, I've seen cases where even git is not fast enough. That's when opcache preload comes into play. It's still better than manually uploading files over FTP.

Having said that, the "most modern" deployment strategy is to spin up a new container with your new code already loaded, point your LB at the new container, and scrap the old container. No opcache issues. No race condition.
