Here is a resume : The test is simple mysql multi-query php script. With freebsd 4.11 on bi-xeon it took 31 sec With freebsd 6.0 on bi-xeon dual core without smp it took 48 sec With freebsd 6.0 on bi-xeon dual core smp it took 62 sec. Any idea of what's go wrong or way to have expected result? Thanks, Eric.
