Should sim performance degrade this much?

Is it normal for a sim's FPS to be 1500, and then when only 8 people arrive, drop to 150-200 and stay there until those 8 people leave, then immediately go back up to 1500?

8 agents does not seem like they should be that much of a drain on sim resources, but whenever more than 5-6 people come to my sim, the whole place goes to hell.

Sounds plausible, particularly if the sim is "low powered", and the people are wearing a heap of scripted attachments.

Are the avs wearing scripted stuff? Animation overrides, prim hair, whatever?

actually more than anything it sounds like there are *ALOT* of repeat sensors in the sim, trained to agents. or objects constantly forcing updates to be sent to all nearby agents. (such as color flashers etc)

people put them out all the time and don't realize they are extremely expensive resource wise, and only get more espensive for each person thats nearby

Were you *actually* getting 1,500 frames per second? If so, one possible explanation for a 10x performance decrease is the overhead for scripts, plus the latency from 8 other people and all the net traffic needed to keep everyone synched up. Actually, for a real-time 3D app, a near-linear increase in latency is pretty darn good. Just think if latency increased by n^2, which can happen in certain systems!
But does it even matter? I mean, your monitor probably can't _display_ more than ~85 fps anyhow, so what's the difference if it's 1500 or 150?

Sleet, a sim's FPS is not frames per second; it has nothing to do with graphics or monitors. It's a snapshot of the sim's overall health.
