nench.sh ("new bench.sh")

Current version always available at https://github.com/n-st/nench

IPv4- and v6-enabled download at http://wget.racing/nench.sh

loosely based on the established freevps.us/bench.sh
includes CPU and ioping measurements
reduced number of speedtests (9 x 100 MB), while retaining useful European and North American POPs
runs IPv6 speedtest by default (if the server has IPv6 connectivity)
has a 10-second timeout for each speedtest, so you don't end up waiting 10 minutes for that one slow speedtest from halfway around the globe — but thanks to the power of curl -w, you still get to see what speed your server achieved during those 10 seconds
successfully tested on Arch Linux, Debian, FreeBSD, and Ubuntu

The script was originally intended to be used only by me, so I didn't put much effort into ensuring safety, security, and interoperability.
I welcome any improvements, just send me a pull request.

Disclaimer

You've probably noticed that the usage examples below have you directly run a script from an unauthenticated source (as so many "easy-install" and benchmark scripts do).

I didn't think I'd have to mention that this is a potential security risk — really, if you're at the point where you're benchmarking Linux VMs, I would assume you know how much harm a rogue shell script could potentially do to your system…

What's more, nench.sh downloads a statically built binary to run the IO latency tests. I assure you it is and always will be a clean unmodified build of ioping, but how do you know you can trust me?

So, basically: use nench.sh at your own risk, and preferably not on production systems (which is a bad idea anyway, because it will hammer your harddisk and network for up to several minutes).

Usage example

(curl -s wget.racing/nench.sh | bash; curl -s wget.racing/nench.sh | bash) 2>&1 | tee nench.log

(wget -qO- wget.racing/nench.sh | bash; wget -qO- wget.racing/nench.sh | bash) 2>&1 | tee nench.log
