I’ve expanded my home network with new switch and I wanted to test the connection speed between different computers. At first, I ran
rsync, but I’ve quickly realised it’s limited by source/destination read/write speeds.
I found better way of measuring connection speed using
# start listening on one computer ie 10.0.0.5 nc -vvlnp 12345 < /dev/null # start broadcasting ~100MB from another computer dd if=/dev/zero bs=1M count=100 | nc -vvn 10.0.0.5 12345 ## 104857600 bytes (105 MB) copied, 8.89602 s, 11.8 MB/s
You can use more sophisticated tools for the same purpose ie.
# install on both boxes sudo apt-get install iperf # start server in one computer iperf -s # measure connection speed from client(s) iperf -c server_IP ##[ 5] 0.0-10.0 sec 112 MBytes 94.1 Mbits/sec
