[MapProxy] FW: Which cache is better

[Andrew, David (DPFEM)]

Hi all,
Totally a newbie regarding all things GIS
I'm trying to establish which cache type is better for a photo cache.

I'm looking to cache the orthographic photo maps for the state of Tasmania Australia, to a zoom level of 18
This will then be used by the new emergency services application to have an offline pre seeded copy.
Around 30 clients, up to 50 in a peak load like New Years eve.

I cannot seem to find anything that defines which cache style would be better or worse.
CouchDB seems interesting and replicatable
Riak seem like very fast fetch
Geopackage looks like we can copy the flat file once we get it.

If anyone has any numbers around which is better that would be great.
At the moment to download the cache takes a week or 2 for levels 17-18 from an arcgis server(10.31 newer than the cache option allow)

Thanks in advance
