> If I attached profiler and look into exactly what is happening.
> 1 request with the profiler connected takes 970ms
> Some observations:
> 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
