RSS mode performance in ixgbe (82599) driver

I'm testing the RSS mode throughput of Intel ixgbe 82599 driver.
My server's specification is Xeon 3GHz (4cores) and PCIe speed is
and DD2 memory is about 600~700MHz.
When I enable the RSS(receive side scaling) mode with 4 Rx queues,
the Rx performance is below than when I use a single queue.
I don't know how the cores operate, whether the cores run in sequence
or simultaneously at the same time.
I want to know the mechanism in general how the multi-cores run
and the reason why the performance of ixgbe driver in rss mode is below
Thanks in advance.
