Initial load performance a bit slow

The initial page load performance of biocache-hubs is slow. For me there is a 6-8 secs lag at the start of the load.

GBIF report this is more like 11 seconds for them from Copenhagen.

Tested today. Same old problem, too many default facets. e.g. in the test, all records search, 19s for the default 12 facets, 2.5s for the minimum of 1.

Not a lot of ideas. Limiting to 4 facets is probably too few for some users. The default 12 I saw today is far too many.

1. Reduce the number of default facets enabled, again.
2. Present all, or most, of the facets collapsed and load data when clicked and opened.

Other opinions required.
