I am working on creating a National WFS dataset, utilising QGIS, PostGIS and Geoserver. The problem occurs when you zoom in and pan around a bit, due to the size of the dataset, some data fails to render. If I connect directly to the PostGIS database, this is not a problem, it only occurs on the WFS. I have advanced styling applied which filters features and applying zoom levels also.

In inserting the WFS I have also selected "Only select features overlapping the current view extent"

Database details:

4 No. Tables
2 Tables containing 1,423,900 Linestring features
2 Tables containing 4,417,900 Point features

I have also done some preliminary filtering of the tables using Views.
The issue is not the Database, its very efficient.

Your help and advice, appreciated,
