Busybox compatible simple speedtest that downloads a file to /dev/null. Useful for sshing into various routers and seeing where the bottleneck is.
#!/bin/sh
# Silly speed test just by downloading a file directly to /dev/null
# Useful on routers which only have busybox installed.

# NOTA BENE: cachefly has worked for over a decade, however they may
# be getting tired of scripts like this. Starting February 2023, their
# 100mb.test file is empty and the 50mb.test file holds 100MB.

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"
