I know I'm coming up with a lot of questions these days... :) Any doc on this sysctl? I think I get the overall picture on what it does, but I'd like to understand whether there are donwsides on enabling this. Like... system running slower or consuming more RAM... incompatible ports or drivers... etc. Any reason not to enable it? I searched the web, but didn't find anything official. bye & Thanks av.
