[mapserver-users] Mapfile VS MapScript performance

[Umberto Nicoletti]

The performance point being made clear by Thomas I think I should mention a
couple of (mostly in functionality) advantages that the WxS wrappers might
have against cgi/fastcgi:

1. it is easy to extend the wrapper to add accounting, logging, caching.
True, accounting and logging can also be accomplished simply by processing
the web server log files but that requires  extra software and might not be
easy to impement in complex situations (think a cached request costs x and
a non-cached y)

2. request preprocessing: filtering layers, redirecting

3. image/response prostprocessing: caching, assembling, watermarking,...
