Hi Shawn,
It may be your facets that are killing you here. As Toke mentioned, you
have not indicated what your max heap is.20 separate facet fields with
millions of documents will use a lot of fieldcache memory if you use the
standard facet.method, fc.
Try adding facet.method=enum to all your facet queries, or you can put
it in the defaults section of each request handler definition.
Ok, that is easy to try out.
Changing the facet.method does not help really as the performance of the
queries is really bad. This lies mostly on the small cache values, but
even trying to tune them for the "enum" case didn't help much.
The number of documents and unique facet values seems to be too high.
Trying to cache them even with a size of 512 results in many misses and
Solr tries to repopulate the cache all the time. This makes the
performances even worse.
Cheers
