6.2 HP ProCurve Switch 2424M
These numbers have been generated by Hewlett-Packard, using the SmartBits tester and the SmartApplications (revision 3.01)
software suite, both from NetCom Systems. This combination is used by most network testing houses and the press to
determine basic performance numbers for networking equipment. Numbers presented here are taken directly from the
SmartBits reports, except for a few calculated values which are clearly marked.
6.2.1 Throughput test
6.2.1.1 100BT
Port pairs active: 26 (24) 100 Mbps full duplex + (2) 1 Gbps full duplex ports = 4.4 Gbps data out of the tester
Test length: 60 seconds
Packet size (bytes) 64 128 256 512 1024 1280 1518
Total Packets 3928578 2602734 1417514 751378 381956 306908 259198
Percentage 60.0 70.2 71.1 72.7 72.5 72.5 72.5
See section 3 for interpretation of the above results.
6.2.1.2 10BT
Port pairs active: 24, = 240 Mbps data out of the tester
Test length: 60 seconds
Packet size (bytes) 64 128 256 512 1024 1280 1518
Total Packets 357144 202704 108696 56400 28728 23088 19512
