[Monetdb-developers] Single column select vs aggregation

Attached is a trace of a single column select operation, with a max, avg 
and equality.

The equality takes about 4 times more time than the avg operation.

 From the plan I see that the operation is executed paralel, but I do 
wonder why suddenly the uselect takes such a high amount of time.
