It is not possible to provide general information regarding hardware and
index sizing. There are too many variables that will affect the
performance.

Memory is by far the most precious resource for Solr performance. An
ideal setup will have enough *extra* memory (beyond the Java heap) for
the operating system to cache the entire index in RAM. The ideal setup
is rarely actually required for decent performance, though.
