Subject: intel 82599 multi-port performance
Date: Mon, 26 Sep 2011 19:26:33 +0900 [thread overview]
Message-ID: <4E805359.2080600@gmail.com> (raw)
Hi, everyone
Now, I'm testing a network card including intel 82599.
In our experiment, with the driver modified with ixgbe and multi-port
enabled,
rx performance of each port with 10Gbps of 64bytes frame is
a half than when only 1 port is used.
The pcie of our server is GEN2 (5x X 8).
Is the result reasonable?
When multi-ports are enabled and 10G stream is inserted to each port,
the maximum performance of each port is a half in our experiment.
Do you think it is a problem of our modified driver or the performance
bottleneck of 82599?
Now I cannot understand our experiment result.
Please give me an advice.
Thanks in advance.
Best Regards,
J.Hwan Kim
