Other people have pitched in with their answers on how to trim down the 
memory footprint for the rooms (which are all legit suggestions), but 
I'm full of questions about what was causing the slowdown in the first 
place, as even without any memory optimization DGD should be able to 
handle 60 megabytes of loaded rooms.  I thought swapping in the 5001th 
room would be as quick as the first.  Unless 60 megabytes is exceeding 
the system's ram and causing a lot of disk access?  Which I doubt is the 
case.  Or is there some "hard limit" in the configuration which is 
treated as a virtual limit on RAM which if exceeded will cause swapping 
anyway?  That wouldn't surprise me, but I haven't endevoured to 
understand all the configuration options yet.
