In any case, on a relatively quiet network, you should expect to see throughput in the 700 KBps or greater range. Throughput of 500 KBps or less is questionable, and 400 KBps or less may indicate a definite network problem.
The following example illustrates the statistics you might see if you ran a simple ttcp test between the stations sheridan and longstreet (two workstations) on a clean network. See the ttcp(1) reference page for details about the many ttcp options.
On sheridan, give the command
ttcp -r -s
You see the following output:
On longstreet, enter the command
ttcp-r: buflen=8192, nbuf=2048, align=16384/0, port=5001 tcp ttcp-r: socket ttcp-r: accept from 192.102.108.4 ttcp-r: 16777216 bytes in 19.99 real seconds = 819.64 KB/sec +++ ttcp-r: 10288 I/O calls, msec/call = 1.99, calls/sec = 514.67 ttcp-r: 0.1user 3.4sys 0:19real 17%
ttcp -t -s sheridan
You see the following output:
The throughput statistics are highlighted in bold and are in units of KBps. The throughput on the station sheridan is 819.64 KBps and the throughput on the station longstreet is 820.02 KBps. Both throughput values indicate good network performance between the stations.
