Question to Lindens- What to look for...

As some of you know, I've been working on a project with many many very small and complex objs.

What I need to know is this:

What do I look for specifically under the Alt-1 stat page when rezzing or manipulating these objs. Also as the number of obj increase, what should I be watching for?

These are about the condition of the sim. I need to know when i'm putting a strain on the sim. I already know of a couple things to watch for but I would like a better grasp on them.

Thank you.

I've fixed most of the problem in the upcoming release, so carefully watching the stats will soon be unecessary (for the reasons you asked about).

The bug was in a somewhat unexpected spot that I don't think was being measured correctly, so it will either not show up at all, or it will be in a single measurement in the ReceiveMsg stat, and you won't see the stat until the simulator has already been lagging.

Here is a recipie to reproduce the bug and bomb the sim (explained here so that you can AVOID doing it):

1. Make several complex primitives: cut, hollow tubes work great, but if the primitives aren't complex enough, just make twice or four times as many.

2. Start moving the primitives such that they all occupy the same spot. As you move them and increase the number of overlaps you'll notice the sim start to become unresponsive (you may have to try to move your avatar to detect the lag of the sim).

2.1 Basically, the sim will lag more as additional complex objects are moved into interpenetration, but it ALSO scales with the number of movements that are being made. So, if you just slam the position of an object into the middle of the collection, it will lag once (you might not even notice it). But if you slowly move the object into place the sim will lag A LOT. If it lags for more than 60 seconds it will crash.

This has been fixed in the next release, and I'll also post this info to the original thread about the problem.
