Thanks for the helpful commentary Christian. Cluster is performing much
better with 50% more spindles (12 to 18 drives), along with setting scrub
sleep to 0.1. Didn't see really any gain from moving from the Samsung 850

Thanks for the tuning tips Bob, I'll play with them after solidifying some
of my other fixes (another 24-48 hours before my migration to 1024

Cullen,
We operate a cluster with 4 nodes, each has 2xE5-2630, 64gb ram, 10x4tb
spinners. We've recently replaced 2xm550 journals with a single p3700 nvme
drive per server and didn't see the performance gains we were hoping for.
After making the changes below we're now seeing significantly better

Hello,
I've been trying to nail down a nasty performance issue related to
scrubbing. I am mostly using radosgw with a handful of buckets containing
millions of various sized objects. When ceph scrubs, both regular and deep,
