Subject: Intel 82599 ixgbe driver performance
Date: Wed, 10 Aug 2011 15:19:34 +0900 [thread overview]
Message-ID: <4E4222F6.7050304@gmail.com> (raw)
Hi, everyone
I'm testing our network card which includes intel 82599 based on ixgbe
driver.
I wonder what is the Rx performance of i82599 without network stack only
with 64Byte frames.
Our driver reads the packet directly from DMA packet buffer and push to
the application
without passing through linux kernel stack.
It seems that the intel 82599 cannot push 64B frames to DMA area in 10G.
Is it right?
If it is the case, what is the bottleneck of 82599?
Thanks in advance.
Best Regards,
J.Hwan KIm
