Amy,

Currently there is no support for keeping an OGR dataset open between layer
renders.  The net result is that the file is re-read for each layer you
want to render.  The connection pooling concept has not been extended to
OGR connections yet.  In fact, I might handle it via a different mechanism.

For now, if you want fast performance, I would encourage you to just convert
the layers you need to shapefiles, or load them into PostGIS.

Best regards,
