I would REALLY like to know how this all affects eachother, how it works in world, what as sim owners we should look out for when trying to keep a lag free region, and to know what it all is broken down. Mempory- What is a healthy number for a sim? What number should be aimed for when keeping a sim lag free? Script memory- How much is too much? How is should each avatar aim for? When living in a community, having residential properties, what is a good amount for each parcel? Collisions- What the heck is it? Debugging and finding lag problems- Ho does mesh affect lag? How much does what each avatar wears and what they do (i.e building, dancing, rezzing, etc) affects lag? Sorry to sound like a noob, but I get so many different answers on all of this, and I would really like to get to the point. I would love a clear guide so any links to blogs, websites or other threads and information is greatly appreciated! Thank you! ~Rene
