Looking over your email history on the list, I was able to determine
some information, but not everything I was wondering about.  I have some

Are you still using the Extracting Request Handler for your rich
document handling, or have you moved Tika processing outside Solr?
If it's outside Solr, is it on different machines?
Are your rich documents still requiring OCR?

Other questions:

On a single Solr server, how much total memory is installed?
What is the total amount of memory reserved for Solr heaps on that server?
What is the total on-disk size of all the Solr indexes on that server?

that server?
-- Multiple replicas must be included here too.
Is there software other than the Solr server process(es) running on that
Are you making queries at the same time you're indexing?
