Thanks a lot for the report. This is really helpful.
I'm working on these issues. There is a part of tuning, but also a part 
of Dart1 rollup that is using a lot of CPU on public.kitware. This 
latter should go away when we stop using Dart1. As you know, we are 
running a lot of services off of public.

I'm keeping an eye on these issues.
