This page displays the performance results for reference NIC 10G and 1G at the Stanford site.

Performance Results - 10G NIC

Myricom Myri-10G NIC to/from Myricom Myri-10G NIC

Omitted since only commodity parts involved. See results at Tests at Dublin Site

Myricom Myri-10G NIC to/from NetFPGA-10G (10G Reference NIC)

Test Setup

This test measures the performance of the NetFPGA-10G (10G Reference NIC) connected directly to a Myricom Myri-10G 10G-PCIE2-8C2-2S NIC.

  • The test setup uses two Core-i7 Linux hosts, where Host A is fitted with a Myricom PCIe NIC and Host B is fitted with the NetFPGA-10G card, programmed with the 10G Reference NIC. Host B uses the NetFPGA-10G Reference NIC driver. The NICs are connected directly via a GORE SFP+ cable between their lowermost SFP+ ports as shown below:

  • Host A has the fixed IP address 192.168.3.1 and runs the netserver component of netperf;

  • Host B has the fixed IP address 192.168.3.2 and runs the netserver component of netperf;

  • For each test, the tcp_stream_script and udp_stream_script netperf test scripts (located in the tools/alpha/ directory) were used;

  • Four tests were conducted in all, using TCP and UDP with- and without forcing CPU affinity (i.e. forcing netperf processes to reside on CPU 1);

  • The duration (in seconds) was reduced to 5 (from 60), resulting in a total test time of approximately 30 minutes.

RealTek RTL8111/8168B 1G NIC to/from NetFPGA-10G (1G Reference NIC)

Test Setup

This test measures the performance of the NetFPGA-10G (1G Reference NIC) connected to RealTek RTL8111/8168B 1G NIC built into our test hosts.

  • The test setup uses two Core-i7 Linux hosts, where Host A has a built-in RealTek RTL8111/8168B NIC and Host B is fitted with the NetFPGA-10G card, programmed with the 1G Reference NIC. Host B uses the NetFPGA-10G Reference NIC driver. The NICs are connected directly via a Category 5e ethernet patch cable as shown below:

  • Host A has the fixed IP address 192.168.3.1 and runs the netserver component of netperf;

  • Host B has the fixed IP address 192.168.3.2 and runs the netserver component of netperf;

  • For each test, the tcp_stream_script and udp_stream_script netperf test scripts (located in the tools/alpha/ directory) were used;

  • Four tests were conducted in all, using TCP and UDP with- and without forcing CPU affinity (i.e. forcing netperf processes to reside on CPU 1);

  • The duration (in seconds) was reduced to 5 (from 60), resulting in a total test time of approximately 30 minutes.
