[OpenLayers-Users] Why WFS Layer is displaying very slowely over Google Map.

Hi,

See : 
http://trac.osgeo.org/openlayers/wiki/FrequentlyAskedQuestions#WhatisthemaximumnumberofCoordinatesFeaturesIcandrawwithaVectorlayer

So 3000 features is quite a lot. Here's a related thread with some 
interesting solutions posted (search for 'indeed' to find the list of 
proposed solutions) :

Regards,
