To be honest, people often advise the opposite, particularly in the region config external host.

I'm not entirely sure why - from my experience FQDNs work fine there (I think the simulator might be storing them as IP 
numbers underneath, I can't remember offhand).

Er, no truth to this at all :)

Again, not true.

This might come from the fact that simulators have a disk asset cache and some people argue that disk is faster than 
database.  However, when I last looked into this there was no conclusive evidence either way with many people saying 
there's no difference and I've yet to see someone produce comparative benchmarks for the OpenSimulator case.

The asset service is not coded to use any Flotsam cache present anyway.
