Review comment:
I've found [this
comment](https://github.com/apache/lucene-solr/pull/940#discussion_r333896831)
how `250` value for `skipCacheFactor` was translated into 10 times slower
performance. But I guess how a query 's`cost` translates to a real performance
cost depends on a query, and having `skipCacheFactor = 10` seems a safer
option to me.
