[Mapserver-users] Map broker?

Mon, 17 Mar 2003 15:08:24 +0100

Hi K,

I've used MapXtreme too, and thus used the MapXbroker handler.

I don't think a broker is needed with Mapserver. Contrary to MapX, Mapserver 
loads (and renders) quite fast, usually within a couple of seconds. A "broker" 
is only necessary when the mapping component is large (and slow) to load, and 
MapX is rather large.

On top of that, I don't think Mapserver is suited for pooling and re-use. Its 
architecture is streamlined to a load-execute-drop method, and I would expect 
severe problem when running it multiple times serving different requests. But 
that's just my impression....

I've used Mapserver with large datasets, vector as well as raster, and only 
experienced slugginess with vector when using "Styleitem Auto" with MapInfo 
tables. But with shape files that's not a problem.

Mvh
