Performance and Recommended Use of AD385A 10 Gigabit Ethernet SR Cards

AD385A Throughput Performance
5
Following are the highlights of the impressive performance achieved during traffic testing at
1500 MTU (as shown in Figure 3):
• Receive traffic achieved 9.11 Gigabits/second throughput with a service demand of
2.20µs/KByte.
• A throughput of 9.47 Gigabits/second was achieved with Transmit traffic, which is the
link rate at 1500 MTU for a 10 Gigabit Ethernet link; the service demand was
1.35 µ s / K B y t e.
• Bi-directional traffic achieved 12.02 Gigabits/second throughput with a service demand
of 1.74µs/KByte. The bi-directional throughput is limited by the bandwidth capabilities
of the PCI-X 266MHz implementation in the rx8640 server and the PCI-X 266MHz
bandwidth limits.
