From the NetPerf web page:
Netperf is a benchmark that can be used to measure the performance of
many different types of networking. It provides tests for both
unidirecitonal throughput, and *end-to-end latency*. The environments
currently measureable by netperf include:
* TCP and UDP via BSD Sockets for both IPv4 and IPv6
* DLPI
* Unix Domain Sockets
* SCTP for both IPv4 and IPv6
So, latency could be tested. According to the man page the tests
available are as follows:
TCP_STREAM
TCP_SENDFILE
TCP_MAERTS
TCP_RR
TCP_CRR
UDP_STREAM
UDP_RR
DLCO_STREAM
DLCO_RR
DLCL_STREAM
DLCL_RR
STREAM_STREAM
STREAM_RR
TCPIPV6_STREAM
TCPIPV6_RR
TCPIPV6_CRR
UDPIPV6_STREAM
UDPIPV6_RR
DG_STREAM
DG_RR
LOC_CPU
REM_CPU
Of course I have absolutely no idea what all of that means!
