Vagrant really kicks arse for creating multiple virtual machine environments.
Monthly Archives: April 2012
I spent a good few hours trying to squeeze some extra performance out of our Vagrant / VirtualBox Development environments.
I was benchmarking different OSs, and virtual hardware configurations.
My guest OS is ubuntu 11. I was experimenting with adding virtual CPUs and suddenly noticed a massive network performance degradation. It seems changing the network adapter to Paravirtualized Network (virtio-net) wasn’t a good idea. Even the Intel PRO/1000 nics were problematic.
Best performance (with multiple CPUs) was PCnet-FAST III (Am79C973).
Hope this helps someone.
I have the most minor of customizations compared to some of my fellow geeks.
export PS1=”\u@`hostname -f`:\w\$”
I like to see the fqdn of my server. At a previous job I might have been logged in to a dozen servers called app01
