If you're rendering raster data only, you don't need a metabuffer.

it depends on many factors... large metatiles are more efficient as
they usually impose less load on the WMS server, but can cause a
significant delay for the end user if you are populating your cache on
demand.
If you're preseeding everything, use large power of 2 metatiles (4x4,
8x8,...). If you haven't pre-seeded, use smaller ones, how small

in the vast majority of the cases, you'll want to have mapcache use
metatiles, be serving PNGs from your WMS server
(image/png in your mapcache ), and storing
your tiles as JPG (JPG in your ). 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.

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?

3 3

Robert,

Regarding labels you can set a metabuffer value in both the mapcache.xml 
and the mapfile.


  
osm-curvature
disk
WGS84
g
PNGQ_FAST
5 5

20
3600
  

and in the mapfile:

WEB
METADATA
labelcache_map_edge_buffer "-20"   ## 
"ows_title" "OSMCurvature"
...
END
END
