> Currently, {{QTime}} uses {{currentTimeMillis}} instead of {{nanoTime}} and hence is not suitable for time measurements. Further, it is really started after all the dispatch logic in {{SolrDispatchFilter}} (same with the top level timing reported by {{debug=timing}}) which may or may not be expensive, and hence may not fully represent the time taken by the search. This is to remedy both cases.
