# Test network throughput.

|
|
# Usage:
|
|
# 1) on host_A: throughput -s [port] # start a server
|
|
# 2) on host_B: throughput -c count host_A [port] # start a client
|
|
#
|
|
# The server will service multiple clients until it is killed.
|
|
#
|
|
# The client performs one transfer of count*BUFSIZE bytes and
|
|
# measures the time it takes (roundtrip!).
