From our performance testing, we are able to improve system response time by crudely eliminating runtime statistics.

Av. system response time(s) from our performance testing, each metric represents a different operation within the performance test;

With statistics enabled; 0.035s/0.245s/1.515s/0.685s/1.975s

With statistics disabled; 0.035s/0.059s/0.578s/0.278s/0.756s

We need to be able to disable statistics in JdbcStatisticsPlugin and ManagedConnectionPoolStatisticsImpl (plus anywhere else runtime statistics are generated) via a configuration option.
