[support] CPU usage

[Steve Power]

heys, i didnt mean to offend.

For a dedicated server, you will be able to deliver a much better user
experience as the performance will deteriorate only in accordance with your
load which you can monitor and plan for.  On a shared host you are at the
mercy of a shared hosting company.  You prob dont need a dedicated host, can
get away with a good vps, but if you've got 30 users hammering the server
for 30 minutes then you have spikes to deal with, which was the bane of
web1.0.  there are more options to deal with this now like automating ec2
instances to come up and down dependant on demand, but they are nothing to
do with drupal.  they are infrastructure engineering issues, which is what i
was trying to say.

It seems to me that the performance issue is an infrastructure, not an
application, performance issue.

Sorry if i came across badly.  been up all day!
