Performance and Recommended Use of AB287A 10 Gigabit Ethernet Cards

8
§ The observed performance results are consistent across all of the same type of I/O slots
of the system; On HP Integrity rx7640, the high performance slots are slots 3, 4, 5 and 6
on each of the I/O Partitions. Performance on other slots will be lower.
§ The core I/O cards in the rx7640 handled minimal site LAN traffic during performance
tests.
§ Processor affinity was used to assign netperf processes to specific CPUs.
Table 1 summarizes the products used to measure the performance.
