[Opensim-users] Default .ini settings question

[Mark Dubin]

There are numerous default settings in OpenSim.ini that are possibly  
related to client performance lag. I cannot (at least readily) find  
explanations of how these defaults affect performance if they are  
increased or decreased or changed. I would like to know, thus this  
posting.

Here are normally used ones I think are relevant to my question, and  
their defaults. If you know the impact of changing any of them,  
please post to this list, or off-line to me by e-mail. I will collate  
the answers and add them to the Wiki in an appropriate manner,  
perhaps as a separate linked page.

I apologize in advance to those who think the answers are self- 
evident :D   Thanks, Mark
