Re: postgres is not using tas

hi tom
If i track a single backend during an 8 read-only queries parallel execution
these are the results(
System call summary:                       Average     Total
Name           #Calls  Time(ms)  Time(ms)

exit                1      0.00      0.00

I think it's a bit excessive for a 8 SMP
