Walkthrough of what I did to increase performance on my Synology NAS box during an expansion, and afterwards.

Performance on Synology RAIDs

(especially while expanding)

Warning: The exact commands may not match for your particular linux OS / Synology(NAS) device. I had to customize the commands after exploring my particular system's setup.

If you're new to linux, or this is a new piece of hardware / a new synology device, jump down to the section called "Inspecting a setup"
