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)
-----------------------------------------
semop 3803 0.20 774.03
select 4 19.58 78.33
recv 1 2.41 2.41
brk 6 0.08 0.48
close 1 0.14 0.14
send 1 0.14 0.14
semctl 1 0.05 0.05
prctl 1 0.01 0.01
exit 1 0.00 0.00
I think it's a bit excessive for a 8 SMP
what do u think?
thanks and regards
