If I attached profiler and look into exactly what is happening.
1 request with the profiler connected takes 970ms
The statement cleanup from the SQL connection pool is about the most expensive operation at 110ms for 57 invocations.
To build the page takes 57 SQL queries, although none are expensive. (all bar 3 report < 1ms).
UsageActionLogger.act consumes 2/3 of the time spent in the request and all of that is in SolrLogger.storeParents
