MIT OrthoServer vs. UMN Mapserver

[Arno roeder]

Our current Mapserver application
http://maps.la.fh-weihenstephan.de:8080/habitalp/overview.html
runs for 11 protected areas in the alps. The HABITALP-project aims for 
mapping of habitats based on aerial photographies. One task is the 
presentation of the landuse cover and the orthophotos with the Mapserver.

Therefore I degraded the original orthophotos with a ground resolution 
of 0,2m to 1m for the max. scale of 1:2.500. Totally that would mean 
about 30 GB of imagery. Furthermore, I made some tiles with smaller 
resolution for smaller scales. In the mapfile I put the different 
resolutions to layers (eg ortho1, ortho2, ortho3) of one group (eg ortho).

Would a OrthoServer significant faster?
