[DeepStream2.0] Correct Performance Evaluation

I evaluate the performance of deep stream 2.0 with sample mp4

I have tested same primary detector renet10 for 3 streams and 30 streams

I notice enable/ disable tiled display plugin may result different fps performance

3 stream (tiled display=enable) : 310fps per stream
3 stream (tiled display=disable) : 30fps per stream

May i know which indicates the correct performance ?
