[Qgis-developer] Geospackage Slow in QGIS

I've just been using the new implementation of Geopackage in QGIS :) However each map render or feature info is very slow for large database files - even with the new GDAL/OGR Geopackage spatial index support. Each time QGIS renders a new map view or executes a feature info it re-opens the Geopackage file in QgsOgrFeatureIterator via OGROpen, and the Geopackage driver open method runs PRAGMA integrity_check which is very slow (4 secs with my 2GB test file). This integrity check is actually a Geopackage requirement.

How can this be fixed? At the in QGIS or GDAL/OGR level?
