I'm not attacking the service level in which your employer provides. I'm simply trying to help guide where I can in correcting the issue immediately and long term. I completely understand the situation and it's a difficult one to be in. On one side you don't have the funds to correct the issue by adding hardware. On the other side, if you offer slower than promised service you have people leave that are paying something. Something I just thought of that may be beneficial is to sell the lower end hosts (44GB RAM ones, etc.) and purchase a couple of used C1100s w/ 128GB RAM from Ebay. While not ideal or elegant if you can sell the old hosts for 50-75$ of a C1100 and get 3x the RAM and performance then that could be a win-win situation.
Nothing you said peanuthead. But memory isn't exactly cheap with our setup. The servers were maxed out with 8 GB x 18 sticks for 144 GB. Ideally we would buy 18 new 16 GB sticks for about $3k.
But again, this is all stuff being worked on. Just need to figure out the best areas to address first, and people were helpful by pointing out the swapped memory usage.
