The time data is all on the X axis. Either you have not set up a second scale for the Y axis for that data (don't ask me how to do this, I'm not a Excel expert), or you have not provided a high enough factor (I cover this in my description of building the chart, using a factor of 10000 or 100000, depending on the pause-time ranges). [I really need to come up with new scripts that plot the pause time ranges for minor and major collections... Yet another task to do in copious spare time.] Also, look at the pause times for the full collections and give me an idea of what their ranges are.
Yes, CMS is the Concurrent Mark-Sweep collector.
Regarding the 500 users in the SLA - is that logged in users, or simultaneous active requests? I ask because in general you can figure about 1 active request for every 10 logged-in users.
Is there any think time in your load testing script?
I still think you need to go with the higher memory settings.
