Rich, 

I have clients who with various fixes through the spring and
summer have achieved respectible, if not exceptional speed
from large MrSID files.  The fixes were quite important. 

There is still the issue that 3 passes are made over RGB files
instead of just 1. 

I don't know why things aren't working with MapServer.  I would 
assume it is something missing from the environment, a permissions
problem or a DLL not in the right place. 

Best regards,
