So then you have one intentionally slow directory ("old/" in this case) and one fast directory?

Personally I'd categorize stuff, but you do you, there really isn't any wrong way to do it, if it works it works :)

I meant you mv into old before it gets too big. I've never actually seen a dir get slow like this. Only seen that with programmatic things like making 1M json files.
