WF is on a Softlayer Dedi right now isn't it? Kind of a downgrade to go a Linode VPS, I don't see dedi on their list, and the highest package they have is 2.8GB ram, 128GB hdd, and 1.5TB bandwidth. Also isn't Xen virtualization slow as fuck?
Afaik the virtualization overhead hovers at 10% of the total node capacity.
And last I checked our bandwidth usage was averaging 350gb per month, so we don't really need that much bandwidth.
We'll be switching to a highly optimized software stack, which will allow us to load the site faster with fewer server resources. If I have time I might make a post about it later.
