I knew about Atom-based dedicated servers, but these plug-class servers take it to whole new level of low-end extreme.
Most of WordPress optimization talk is about surviving on shared hosting or scaling up.
I got curious - how viable is it to run WordPress on such low-end, but dedicated hardware? At which point will CPU or slow storage become bottleneck? How will it compare to generic shared hosting (even lower resources, but no neighbors and freedom to optimize).
