133MHz bus for different types of traffic combinations (Ethernet transmit, Ethernet receive,
Ethernet bi-directional) when the recommended models are used.
The AB287A has excellent sustained performance at both 9000bytes MTU and
1500bytes MTU.
Figure 2 Performance Summary
10 Gigabit 9000MTU Performance
Following are the highlights of the excellent performance achieved when operating at
9000MTU:
• Receive traffic achieved a sustained throughput of 7.90 gigabits per second,
amounting to about 92.8% of the theoretical maximum bandwidth of the PCI-X
133MHz bus. The service demand (which the amount of time it takes the CPU to
handle one kilobyte of data) was 1.4µs/KByte.
• The transmit throughput was 7.56 gigabits per second, which is about 88.9% of the
theoretical maximum bandwidth of the PCI-X 133MHz bus. The service demand was
1.1µs/KByte.
• The bi-directional throughput was 7.64 gigabits per second, which is approximately
89.8% of the theoretical maximum bandwidth of the PCI-X 133MHz bus. The sevice
