Thank you for the answer, Todd. 15.10.2014 23:07, Fujinaka, Todd пишет:
Can you send us the output of "lspci -vvv" (run as root) and ethtool -s?
Attached.
You are right. When using both adapters remote memory is used. Remote memory is not used when any of two adapters run alone. Results are in attachment too. Why this happen?I'm guessing that you're trying to use memory on remote NUMA nodes. You can try running: https://software.intel.com/en-us/articles/intel-performance-counter-monitor-a-better-way-to-measure-cpu-utilization
While it sounds good in to utilize all the NUMA nodes, it may not be the most efficient thing to do.

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.
