AW: [Mapserver-users] Map broker?

[Arnulf Christl]

Hi,
use shptree to create indexes, then it should be fast enough.
If that is still not fast enough, then you have to get your project
modified. Add thinned & generalized layers at higher zoomlevels and use
logical zoom limits for the base maps.
There currently is no map server around we would know of which is faster
than UMN MapServer and we have tested quite a few! We are using it with
several customers each between 3 to 10 GB of shape and its OK. Could be
faster, yes / but its better than all the rest.

Never expect any data crammed map server to be able to answer more than 1 or
2 requests per second because of the sheer amount of data. Some of our very
heavy projects need ut to 5 s per request. The users will tolerate that if
you can explain them that the quality and amount of data is good. It is a
completely different world to what standard web servers do.

Regards, Arnulf.

Has anyone of You any experience with MapServer and large amount of
data. By large amount of data I take approximately 300MB of shapefiles.
I think that MapServer's current architecture is not suitable for this
use (when taking into account couple hits per second).

I got some knowledge of MapInfo MapXtreme - there is a mechanism of map
objects broker which is preinitializing map objects and "renting" them
on request. Don't you think that it would be great to have such
"map-buffering" mechanism? I'm inspecting MapServer's code to find some
clues wether it is hard to do it or not...
