Well if this is a question of two cheap servers vs one expensive one, then
it probably amounts to about the same thing, since you're using vserver
anyway. I was referring to those who have a cheap dedicated server all to
themselves, i.e. to run a low volume website (or two).
This isn't as much off-topic as it may seem, BTW. One of the things that I
believe will lead to wider use of virtualization/separation technologies
such as VServer is the consideration of energy consumption and rising
energy costs. As servers get faster, they will consume more power (9W for
a 90MHz Pentium vs 75W for a 2GHz), and at some point this will become
significant enough where even a "cheap" box would not be justifiable on
its own because of how much electricity its "low end 5GHz" processor
consumes. So we're going to be back to mainframe line of thinking, where
you don't associate physical boxen with their function ("mail server",
"web server", etc.), but get one BIG box and segment it.
