HP ProCurve Switch 4000M / 8000M / 2424M / 1600M Reviewer’s Guide
6. Appendix A: Performance Figures
These numbers have been generated by Hewlett-Packard, using the SmartBits tester and the SmartApplications (revision 1.70)
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. The maximum number of test ports with SmartBits at
10Mbps or 100Mbps is 80. SmartApplications v1.70 does not support full duplex streams even when the switch is configured
for full duplex. Numbers presented here are taken directly from the SmartBits reports, except for a few calculated values
which are clearly marked.
See Section 3 for an analysis of these numbers.
