|
|
|
- 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)
|
2017-05-08 21:30:06 +02:00
|
|
|
- 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

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).
