Performance Summary
The AB545A card provides excellent performance when used in accordance with the
recommendations in this paper. Figure 3 summarizes the performance results possible when
combinations of Gigabit Ethernet transmit, receive, and bidirectional traffic are run through
the card with a standard 1500-byte maximum transmission unit (MTU).
Figure 3
AB545A Throughput Performance Summary in
rx4640
The graph shows the average of sustained transmit, receive, and bidirectional throughput
relative to link rate measured on:
• 1, 2, 3, or 4 Gigabit Ethernet ports.
The AB545A has excellent sustained performance. Averages range from 77.3 - 99.7% of
link rate on the rx4640 system with different combinations of traffic types. The summary
includes results for all 4 ports running sustained simultaneous traffic.
Many of the different types of traffic combinations achieve link rate and will be discussed in
more detail later in the document.
