[netperf-talk] 802.11g udp and tcp bandwidth test

[Max Ip]

Hi all,

I have network connection of two laptops connected through wifi in
Access Point mode with bandwidth 54Mbps (802.11g).

Now, to test the throughput, I used the following commands:

netperf -H 192.168.1.4 -t TCP_STREAM -l 10 -c

This gave me a TCP throughput of 11.89 Mbps.

netperf -H 192.168.1.4 -t UDP_STREAM -l 10 -c

This gave me a UDP throughput of 22.5 Mbps.

I think the UDP bandwidth is ok to have 22.5 Mbps (around half of
54Mbps for half duplex channel). However, how can TCP bandwidth be
just 11.89 Mbps?

Could anyone help me?

Thanking

Max
