Recently I've moved my mysql setup over to Adam's VAS. I run two fairly active sites that are php/mysql based and have one service that depends on mysql. While they weren't necessarily hungry for space the combination of the memory usage (15.2% on my L192) and IO usage of serveral joins was constricting, to say the least.
It's obvious that this type of VAS is crucial for solutions like Linode where you have to be mindful of memory and IO usage, especially if you have an L64. Great work and foresight on this product Adam, it's made my experience on Linode even greater (just when I thought it wasn't possible). Now if only I had a better way to manage my spam/virus that come into my Linode.
