Gigabit Ethernet Only Performance
Figure 4 shows the performance results of the Gigabit Ethernet ports when unidirectional
Gigabit Ethernet traffic using a standard 1500-byte MTU is being run through the card.
The following highlights show the exceptional performance achieved during Gigabit
Ethernet traffic testing:

AB290A Gigabit Ethernet Throughput in rx4640
• Transmit traffic achieved link rate on the rx4640 reaching 948 megabits per second on
one port and 1.896 gigabits of application data per second of throughput using both
1000 Base-T ports.
• Receive Traffic achieved link rate on the rx4640 reaching 948 megabits per second on
one port and 1.895 gigabits per second using both 1000 Base-T ports.
