[Mapserver-users] Mapserver WFS performance

[Bart van den Eijnden]

Hi list,

Today I was testing Mapserver WFS on a shapefile of 450 Mb in size with a 
quadtree index.

I am using no Filter (no BBOX) but only a MAXFEATURES parameter in my URL. 
Perhaps this is not the intention of Mapserver WFS, but this is also a 
potential for people to "attack" the server. It looks like Mapserver is 
reading the whole shapefile in order to give back the first 1 or 10 
features. I stopped testing at 10 features because of the long response 
times.

These are the results of my performance test:

MAXFEATURES    RESPONSE_TIME [seconds]
1              192
10             210

Any comments on this? Am I doing something wrong?

Best regards,
Bart
