The nettest and nettestd commands invoke client and server
|
||
|
|
programs that are used for timing data throughput of vari-
|
||
|
|
ous methods of interprocess communication. For TCP and
|
||
|
|
OSI connections, the nettest program establishes a connec-
|
||
|
|
tion with the nettestd program, and then it does count
|
||
|
|
writes of size bytes, followed by count reads of size
|
||
|
|
bytes. For UDP, the nettest program performs only writes;
|
||
|
|
reads are not performed. The nettestd program, if used
|
||
|
|
with UDP connections, reads the data packets and prints a
|
||
|
|
message for each data packet it receives. The number and
|
||
|
|
size of the reads and writes may not correlate with the
|
||
|
|
number and size of the actual data packets that are trans-
|
||
|
|
ferred; it depends on the protocol that is chosen. If you
|
||
|
|
append an optional k (or K) to the size, count, or bufsize
|
||
|
|
value, the number specified is multiplied by 1024.
