Test your net.ipv4.tcp_congestion_control config with iperf

client.bash

algos=$(find /lib/modules/`uname -r` -type f -name "*.ko" | sed -n "s/.*ipv4\/tcp_\(\w*\)\..*/\1/p"  | sort -u)
server="XXX.XXX.XX.XXX"
filesize="10M"

for i in $algos
do
    echo "Test $i";
    sudo modprobe tcp_$i;
    for t in {1..3}
    do
        sudo iperf -c $server -Z $i -n $filesize
    done
done


# just simply run the iperf in the server and run this script in client
