Hello just a note that I have created a group in SL focused on discussing issues and answering questions related to sim maintenance, performance, and security. I started this group because I could not find any similar resources either in world or out. If you have experience building and running sims and can add your expertise, or are responsible for some aspect of running a sim, please join.
You can find the group by searching in groups for Sim/performance/maintenance.
Thanks.
