| Number of CPUs: | 8 |
| CPU Speed (GHz) | 2.80 |
| Chipset: | Intel 5520 (Tylersburg) |
| Interrupt Type: | MSI |
| Write Combining: | Enabled |
| Linux Kernel: | 2.6.18-92.el5 |
| Myri10GE Driver version: | 1.4.4 |
| Hardware Write Speed (Gb/s) | 25.7 |
| Hardware Read Speed (Gb/s) | 25.3 |
| Hardware Read/Write (Bidirectional) Speed (Gb/s) | 49.7 |
| Transmit | Receive | |
| Netperf TCP STREAM, MTU 9000 (Mb/s) | 9910.19 + 9910.17 | 9910.19 + 9910.17 |
| Netperf TCP SENDFILE, MTU 9000 (Mb/s) | 9910.25 + 9910.23 | 9910.25 + 9910.23 |
| Netperf UDP STREAM, MTU 9000 (Mb/s) | 9924.04 + 9924.06 | 9924.04 + 9924.06 |
| Netperf TCP STREAM, MTU 1500 (Mb/s) | 9467.87 + 9467.30 | 9467.87 + 9467.30 |
| Netperf TCP SENDFILE, MTU 1500 (Mb/s) | 9464.61 + 9464.38 | 9464.61 + 9464.38 |
| Netperf UDP STREAM, MTU 1500 (Mb/s) | 9159.45 + 9065.97 | 9159.45 + 9065.97 |
Note:
Since the DMA benchmark in the Myri10GE driver cannot express aggregate DMA bandwidth of both NICs at once, we instead ran a custom DMA benchmark which carefully synchronizes both NICs and measures aggregate DMA bandwidth.
The transmit and receive numbers are presented as (port0 + port1).
