From f6e7302cb49ee227aed537026d19f68528051dfd Mon Sep 17 00:00:00 2001 From: Kay Ousterhout Date: Sun, 20 Jul 2014 20:18:18 -0700 Subject: Improve scheduler delay tooltip. As a result of shivaram's experience debugging long scheduler delay, I think we should improve the tooltip to point people in the right direction if scheduler delay is large.
