Hi all,

Ran a query containing a join on two relatively large datasets. Added the fullstimer option.

In the log I see the CPU time is 50% higher the Real Time. How come the CPU time is higher than the Real Time? Do the statistics of multiple CPU's used in the query get aggregated?

Regards,
Tomas.

Yep.

That's because you're running on a multi-cpu platform.

The reported CPU time, sums every CPU time dedicated to the task.
