Thanks Thomas. I do not have labels, so would you still recommend metatiles for 
performance reasons? Would you suggest 3 3 or 5 5 for a Mapserver WMS backend?

<metatile>3 3</metatile>

in the vast majority of the cases, you'll want to have mapcache use metatiles, 
be serving PNGs from your WMS server (<format>image/png</format> in your 
mapcache <source>), and storing your tiles as JPG (<format>JPG</format> in your 
<tileset>). If you need to preserve transparency on your orthophoto edges, you 
can choose to store the tiles as a"mixed" format instead of pure JPG.
