When I'm playing with a new VPS, the first thing I like to do is run a benchmark to see if I've got a good deal.

Running this in a terminal will start the benchmark (only need to install time and bzip2 once)

apt-get install time bzip2
bash <(wget --no-check-certificate -O - https://raw.github.com/mgutz/vpsbench/master/vpsbench)

You'll get an output similar to this

Just got this new toy, off to play with it ;)
