But I don't know how to use these parameters with qgis
Also, WFS has been improve with Mapserver7, much much faster when using
filter on a postgis database. If you plan to use WFS I suggest you update
to MS7, if you have any control on the server of course.

Re: RE [Qgis-user] wfs usage for "big data"
It is almost POINT Geometry. The datasource is a Postgis Database. The
server
ist the UMN Mapserver.
Is there perhaps a posibility to customize the request in QGis, so that
you for
examle take the first 5000 object, and after this the next 5000 and so on
?
