 ## Motivation
 I have been running a ceph cluster in my homelab for about 2 years now, but never properly benchmarked it, let alone wrote down my findings or any potential conclusions.
+I still don't know what kind of performance to expect or what would be considered good or expected for my setup, but having numbers without context is still better than no numbers at all.
 
-## Setup everything for the Benchmarking
+## Benchmark Setup
+This covers all the steps I did to setup my benchmarking, so anyone could follow along and for me to reference later to repeat benchmarks properly.

+1. Overall I am satisfied with the performance of the cluster for my current use-case
 2. There is a lot of room for improvement in the low queue-depth range
 3. The network is not really a limiting factor currently
     - None of the nodes in the cluster exceeded 500MiB/s of TX or RX, so there is plenty of room for growth
