The system runs on

and the latest version of WordPress (always up to date) and a bunch of plugins. Including an old (the only old one) version of Quick Cache (20111203), since that was the best one before they changed it into a free and paid version which contained a lot of bugs. I did switch that cache plugin off trying to trouble shoot and find out why the pages were loading so slow. It did not make any difference.
I tested again this morning, enabling the counters.

The difference is not that big anymore, but stil a 4 seconds difference. The biggest time spend was on the "wait time" (or time to first byte), which was 2,9 seconds (http://fpt.pingdom.com#!/cvdCC6/http://supersnelgezond.nl/zuur-base-tabel-alkaline-dieet/).
Still love your plugin, though. :-) I am only using is without the counters now.
Hope this helps, Carlo
