Could this be a 5.2 performance issue ?
In spite of certain areas where the 5.x series performance is known to
be much better than 4.x (e.g networking), this may not be manifested in
practice for a complete application.
(e.g. I am still running 4.9 as it outperformed 5.1 vastly for a ~100
database sessions running queries - note that I have not tried out 5.2,
so am happy to be corrected on this)
