Hi Merlin,
I am sure you can get good performance with these.
I simply focused on the part where seb said he was testing his app, and
since you can get some really high data throughput (by my very modest
standards anyway) with a good machine, I wondered why he did it.
Maybe seb is planning for an application that already has hundreds of
users after all, I did oversee that option.

Could you elaborate on the complexity you mention ? Setting up a machine
on Amazon, even with a script, is quite simple. As for the pricing you
give, it can be matched on Amazon using Micro or small instances, which
would be adequate given your load average.

Well, it _has_ to be more complicated to use AWS than a bare machine,
because of the added layer?
