---------------------------------------------------------------------
Nitsan Wakart was looking at the JsonFaceting benchmark to lend some insight
on the fairly large garbage creation that occurs when faceting using docvalues
and pointed out that variability between runs was too high. I just pushed a
revision that fixes some incorrect ThreadLocalRandom usage I thought I had
removed and I pinned the seed that used for randoms. That should improve the
situation.

> I’ve spent a fair amount of time over the years on work around integrating
> Lucene’s benchmark framework into Solr and while I’ve used this with
> additional local work off and on, JMH has become somewhat of a standard for
> micro benchmarks on the JVM. I have some work that provides an initial
> integration, allowing for more targeted micro benchmarks as well as more
> integration type benchmarking using JettySolrRunner.
