The following charts show the results of the throughput tests.
Cisco fills available bandwidth. The Cisco 5520 can effectively utilize available 20-Gbps network
bandwidth at packet sizes from 256 to 1,374 bytes. The Aruba 7210 fills 10 to 25 percent of available
bandwidth at packet sizes up to 516 bytes.

Unaffected by number of clients. The Cisco 5520 controller proved better overall throughput with client
tests for a wide range of packet sizes.
tests for a wide range of packet sizes.
Cisco outperforms Aruba. At small packets sizes up to 1,374 bytes as well as with the IMIX packet-size
mixture, Cisco's latest 8540 controller roundly outperforms the Aruba 7240.
mixture, Cisco's latest 8540 controller roundly outperforms the Aruba 7240.
Aruba throughput depends on big packets. The Aruba 7240 can make good use of its 40 Gbps of network
bandwidth only with large packet sizes. The Controller datapath CPU hits 90-95% limiting its ability to pass
more traffic.
