[Mapserver-users] Storing database connections in a CGI session

[Bart van den Eijnden]

Hi Richard,

what is the absolute difference in performance (time) between Mapserver en 
ArcIMS? And can you tell some more about how you did the tests (number of 
concurrent users, which tool etc.)?

I think the difference is not only in the database connection, but also in 
the caching of data. Although I do not know how ArcIMS works exactly 
behind the scenes ofcourse.

An alternative to CGI sessions is the fastcgi approach. Frank Warmerdam 
did some work on this a few months ago, but I don't know if there any 
useable results.

Best regards,
Bart
