netperf

The above netperf output shows this NFS server was able

to send TCP/IP data to the client at a sustained rate of

~59.5MB/sec during the 10 second test.

Netperf is a benchmark utility that can measure the performance of many different

types of networks. Like ttcp, netperf measures throughput without relying on any

filesystem resources. The environments currently measurable by netperf include:

• TCP and UDP via BSD Sockets

• DLPI

• UNIX Domain Sockets

Rick Jones, of HP’s Infrastructure Solutions and Partners group, developed netperf

back in 1993, and he has continued to add new features and capabilities to the

program as new networking technologies became available. The best source of

information is the official netperf website: http://www.netperf.org.

As with ttcp, any netperf results should not be interpreted as potential NFS

throughput values.
