- 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.
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).
