| Type of performance test: |
High throughput, Intel gigabit controller, Intel Xeon platform, simultaneous 2-port test |
| Gigabit card: |
Model 5262 dual-port PMC (PCI-X mode) |
| Platform: | VxWorks 5.5, 2-GHZ Xeon, SuperMicro P4DL6 mainboard, Serverworks LE system controller |
| Frame size: |
1500 bytes |
| Sustained throughput: |
246MB per port (492MB/sec total) |
| Gigabit controller: |
Intel 82546GB |
|
Description:
The following driver-level statistics for ports 0 and 1 show both ports running
a high throughput test simultaneously at about 246 megabytes per second per port
for a total system throughput of 492 megabytes/sec sustained (3.93Gb). Frame rate
is about 164,000 1500-byte frames per second on each port for a total of about
328,000 fps. Gigabit controller used for test is Model 5262 dual-port PMC (PCI-X mode) on a 2-GHZ Intel Xeon system (SuperMicro P4DL6, Serverworks LE chipset) in 133 MHZ PCI-X mode. Operating system is vxWorks 5.5. Statistics highlighted in bold show throughput in both bytes and frames per second.
