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?
