Netperf testing gives low throughput

[pacc-314]

I am running netperf test from a client server with netserver already started on peer server. I constantly see throughput percentage less than 50 %. Can you please let know if we are running test wrongly? The

avocado run /var/tmp/avocado/selftests/unit/utils/netperf_test.py -p peer_ip=10.x.x.x -p interface=bond0 -p peer_user=root -p TIMEOUT=720 -p NETSERVER_RUN=0 -p EXPECTED_THROUGHPUT=90 -p duration=60 -p minimum_iterations=1 -p maximum_iterations=5 -p option='TCP_STREAM --'

It seems to compare the throughput value with below file to get percentage throughput

cat /sys/class/net/bond0/speed
