I recommended no such thing, Kayla... I said there is nothing in WHM that he can do to tweek it - he'd have to go right to the server configs - apache and mysql...

If you know your site is already optimized enough and if there is nothing obvious that needs modification, a RAM upgrade is a quick way to stabilize the server. In the end it really comes down to your visitors and all of the requests they are making to your site. Even with all of the optimization possible for your particular application, you still need a more powerful server as times goes on in order to keep the system running smoothly under pressure.

I agree. but 5-20% CPU utilization in this case really does indicate that the problem was surely a RAM shortage. There are ways to tweek apache and mysql to optimize memory use - and you (terrabyte) need to look into those and see what you can do to tweek your site. I don't think Drupal is the most optimize CMS, either. Did you turn on any CACHEING that is available within the system? CACHING will improve performance by keeping static representations of frequently accessed content and not re-query the database for each hit.
