[support] Dev Site Impact Impact on Server Resources

[Sohodojo Jim]

Shai,

	Keep in mind, too, that if by resources you are concerned about such
things as RAM and CPU usage on the server, a simple Telnet connection and
'top' command can tell you a lot about your site. The threads/processes
kicked off by your server are often much more the source of resource
consumption than the Drupal site itself (although you cannot starve a site
on memory based on how many modules you need).

	I have found over the years that hosting services have very
different and sometimes nonsensical assumptions about what a basic Apache
(in my case) server config should be. For a module-intensive but low
concurrent user scenario, you can very likely reduce the minimum number of
thread/processes instantiated as well as reduce their lifespan and get good
performance with limited resources. 

	Under Apache, such config settings as StartServers, MinSpareServers,
MaxSpareServers, ServerLimit, MaxClients, and MaxRequestsPerChild can have a
big impact on your Drupal site resource consumption and site performance.

	BTW, I am no expert in these low level regards but can only speak
from WTF?! experience.
