Off topic and pure speculation. With 400k refs, each one 20 byte in length, the pathname part only can take 7MB. Perhaps packed-refs should learn prefix compressing too, like index v4, to reduce size (and hopefully improve startup speed). Compressing refs/heads/ and refs/tags/ only could gain quite a bit already. -- Duy -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
