# 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!).
