20.000 nodes if far too much, as the resultGeometry is transfered into 
the Client into a GeoJSON.

There is no Mapbender parameter which you can change.

But you could change the WFS access on your data:
If you have your data in a PostgreSQL database you can easily change the 
query and do a search on the boundingbox of your polygon or on a 
simplyfied polygon with less nodes.


CREATE VIEW query_mytable AS
SELECT gid, name, st_envelope(the_geom) as the geom FROM mytable;


CREATE VIEW query_mytable AS
SELECT gid, name, st_simplify(the_geom,100) as the geom FROM mytable;

I hope this information will help.

Best regards

Astrid
