Mapserver vs ArcIMS [transfer from the wiki site of mapserver]

It is interesting to see.

ArcIMS evaluation:

 
"Advantages of ArcIMS? * Distribute applications over multiple machines * native integration with the Geography Network.
Mapserver can be made to work within the Geography Network. * Using DES software to handle routine tasks like making the map
Services (Map Files), designing web sites, etc. * supports more data formats-especially raster * better support for storing spatial data in RDBMS through SDE * You don't have to try to operate a relatively unknown product
(Mapserver) and philosophy (Open Source)
 

 
"Disadvantages of ArcIMS? * Speed (even running mapserv as regular CGI it is much faster) * Resource hog * limited OS (no Linux) * less stable. My ArcIMS? Experience is on NT so that may be more
A reflection of the OS than ArcIMS ?. * Poorer support * Source Code unavailable * cost"
 

Speed: Most everybody said that mapserver is faster * although theoretically this shoshould not be the case since mapserver is a CGI while ArcIMS? Is a Java app. (* nobody claimed ArcIMS? Is faster, just not everybody made a speed comparison)

Documentation and installation, we think mapserver is actually better.
