From 624227854e619d1bf555445f3bc38730fb9278c4 Mon Sep 17 00:00:00 2001 From: Prakash Surya Date: Fri, 3 Jan 2014 10:36:26 -0800 Subject: Disable arc_p adapt dampener by default It's unclear why adjustments to arc_p need to be dampened as they are in arc_adjust. With that said, it's removal significantly improves the arc's ability to "warm up" to a given workload. Thus, I'm disabling by default until its usefulness is better understood.
