[Opensim-users] Conversion to VAR region (UNCLASSIFIED)

We have run into a number of issues while attempting to use var regions.  Our largest var region was a 6x6, but we have other configurations as well.  Here is are a couple of things we encountered:

1)  If var regions and normal regions share a border, we saw instability in the var region when attempting to cross from the normal to the var.  It didn't crash every time, but it did crash enough to raise concerns.
2)  Be mindful of your prim budget.  It is easy for your content creators to forget they are still dealing with a sim that is only using the same CPU/memory resources as a regular region.  As a consequence it is easy to overload them.

We had to correct the statistics mechanisms inside of OpenSimulator to attempt to debug this.  In the end, we parked that work and found it was easier to chop the var region up into regular regions.  Our needs included stability, so if you can live with the occassional random crash - you should be fine.

Subject: [Opensim-users] Conversion to VAR region

I have been experimenting with converting to a var region for my 8x8 group of regions.  Only 17 of them are land regions with the rest oceans to give everyone a great view.
 
My current thinking after trying several different combinations of var regions from one giant down to a bunch of 2x2’s and all sorts of different mixtures in-between, is to make it into a new 9x9 area, with 9 3x3 var regions next to one another.
 
These would run as three vars on each of my three servers which would evenly distribute the load.
 
Does anyone have experience with running three var’s of this size on a single server, and how efficient is it?
 
Another question I have is about using the OSSL functions to make the different parcels.  My question: should I make them one at a time using the OSSL functions, or can I make them all at once using one large script with each parcel in it’s own little section?
