Hi,
Really, it is not as simple to answer as it may look like. How important
is it that your web server is accessible all the time? Can you accept
rejected requests during peaks? Can you accept delays in serving requests
during peaks?
There is no general guideline, and there can never be, because it is all
relative, and unique to each situation and organisation. Some will want to
use 95% of the CPU all-the-time, and does not care about delays or
down-time (for some clients) during peak situations. Others care about
this very much, and need to have an average usage of 10% because it is
extremely critical that the web server can respond in a timely fashion.
If i were to give you any numbers, i would say that about 70-80% CPU usage
on average is reasonable for many organisations, and for memory - the more
memory you have the better.
But remember that this was given with no insight at all on your needs. It
may, or may not, be suitable in your situation.
