A lot of us just run with a small single VPS/Cloud server like on Linode
or Rackspace cloud.
It's not the best performing sometimes. But the traffic weight and cost of
a single small wiki doesn't really justify running two servers.
You kind of need to be running multiple wikis (or one insanely large one)
to justify the server separation.
