Or at least the docs say that. If I am wrong the docs need updating and it is defenitly a bug as netstat -m output is different.

Re: mbufs on 5.3-STABLE possible bug
Sorry, yes have tried it, I am still seeing a negative perofrmance difference with the setting on 0 but the gap is greatly reduced and its something that is a lot more acceptable, at most it has been 10% worse then if left on auto or set to a value. Let me know if there is any specific types of tests you want doing.
