comment How to improve Intel X520-DA2 10Gb NIC throughput without Jumbo packets
In the same spirit, I plan to try two physical cards, one per CPU socket (or per NUMA node), and see if it makes any difference.

I have seen the cards hit a performance wall with large number of clients, prompting me to use link aggregation. In retrospect, that was a questionable call. I need to try this again. Great suggestion, thanks.

I have already mentioned that I maxed out the number of Rx/Tx buffers as a first step. The card severely underperforms if that's not done.

Absolutely. Thanks for a great pointer.

Why is it that Intel's older NICs support RDMA, whereas newer ones say N/A? intel.com/content/www/us/en/network-adapters/…

Are you talking about increasing MessageNumberLimit value in the registry? msdn.microsoft.com/en-us/library/windows/hardware/…

This is a dual-core rack mount Dell Precision Workstation R7610. Screen capture is there to accentuate the fact that most modern (even simple) PCIe devices support message-singnaled interrupt scheme.

This is a new rack mount workstation product that blurs the lines between server and workstation. I generally like it for our application, apart from the issue above.

Amazon Mechanical Turk, cute. I'll go through the motions.
