Megaprims revisited.

April Fools? No, I don't play that....

So, Megaprims, talked about 'em before and how I don't use them because Linden has been back and forth about it too many times to count.... seems the current thinking is that a certain size is going to be ok, bigger isn't.... well... maybe not. See why I don't use them? The creators of the world aren't even sure. As seen on the SecondLife Official Blog:

DEV-12585 Details: Megaprims discussion # who knows by now? attempt at a joke
In office hours discussions it had seemed that no one was using megaprims
over 256m in general ways, but Andrew had the good idea to scan the grid just to
check… What we found surprised us. There are over 80 regions using larger than
256m megaprims, in almost all cases in order to generate an artificial horizon -
either sky or water.

Given the number of these completely legitimate builds that would be affected, and the ability to implement megaprim clamping code essentially on a moment’s notice if it seems appropriate, we reached a new and somewhat different conclusion. In addition, I will be doing some performance and capacity work to determine specific overhead for this amongst other cases so that we understand the real impact of these on region design.

We have now decided that the best path will be to not restrict megaprim size to 256m as we had previously discussed at length (for months), but to only limit them to 64k meters, and have an upcoming project create better tools for managing large
prims, both in terms of tracking them and providing methods to prevent mis-use
that create problems for residents in overlapped parcels (where a megaprim
overhangs their property, for instance).
