No. Startup/re-open time is around 1 minute for the Solr instance, but
due to <long story> we are currently doing nightly updates only.

That is correct. We haven't experimented with segment based faceting
yet, but from what I can see you get faster startup at the cost of
slower subsequent queries due to costly merging. When we increase the
frequency of updates (working goal is every 5 minutes), we will have to
look into this.

On that note, Lucene's faceting with a central repository for the facet
terms looks very interesting as it opens up for both fast startup and
fast queries.
