How deletes affect on QPS

Hi,

Somebody on IRC has recently asked about when to do solr index
optimization. I pointed out, that deletes in the index could be a good
reason to periodically optimize, here is a nice post with QPS statistics
per query type (though on Elasticsearch site, it is relevant, because
essentially the post is on Lucene level):
