Motherboard performance with Myri-10G "Gen2" (5.0 GT/s) NICs |
| Motherboard: | Asus RS500-E6-PS4 |
| CPU Type: | Intel Xeon X5570 (Nehalem EP) |
| Number of CPUs: | 8 |
| CPU Speed (GHz) | 2.93 |
| Chipset: | Intel 5520 (Tylersburg) |
| Interrupt Type: | MSI |
| Write Combining: | Enabled |
| Linux Kernel: | 2.6.18-128.1.16.el5 |
| Myri10GE Driver version: | 1.5.0 |
| Hardware Write Speed (Gb/s) | 25.6 |
| Hardware Read Speed (Gb/s) | 25.3 |
| Hardware Read/Write (Bidirectional) Speed (Gb/s) | 49.9 |
| Transmit | Receive | |
| Netperf TCP STREAM, MTU 9000 (Mb/s) | 9910.17 + 9910.18 | 9910.17 + 9910.18 |
| Netperf TCP SENDFILE, MTU 9000 (Mb/s) | 9910.25 + 9910.25 | 9910.25 + 9910.25 |
| Netperf UDP STREAM, MTU 9000 (Mb/s) | 9924.50 + 9924.60 | 9924.50 + 9924.60 |
| Netperf TCP STREAM, MTU 1500 (Mb/s) | 9476.61 + 9476.61 | 9476.61 + 9476.61 |
| Netperf TCP SENDFILE, MTU 1500 (Mb/s) | 9448.67 + 9454.31 | 9448.67 + 9454.31 |
| Netperf UDP STREAM, MTU 1500 (Mb/s) | 9318.20 + 9215.50 | 9318.20 + 9215.50 |
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).
