Subject: performance of two 82599 nics at a host
Date: Wed, 15 Oct 2014 17:52:23 +0700 [thread overview]
Message-ID: <543E51E7.3020206@eml.ru> (raw)
Hello, everyone.
I have two 82599 nics connected to different numa nodes. Each nic can
recieve up to 12Mpps 64-byte packets.
But when I send traffic to both nics only 5Mpps+5Mpps can be recieved.
May someboby help if it's driver, kernel or hardware bottleneck?
Configuration:
2 x E5-2667 v2@3.30GHz
3.14.19 kernel, 3.22.3 ixgbe
8 queues at each nic with affinity set
NIC1
