Для проверки пропускной способности сети можем воспользоваться следующими сайтами и сервисами.
Linux cli:
Проверяем какая скорость установлена на сетевой карте:
# ethtool ens192 | grep Speed
Speed: 10000Mb/s
wget -O speedtest-cli https://raw.githubusercontent.com/sivel/speedtest-cli/master/speedtest.py chmod +x speedtest-cli # ./speedtest-cli Retrieving speedtest.net configuration...

# wget https://github.com/ddo/fast/releases/download/v0.0.4/fast_linux_amd64 -O fast # chmod +x fast # ./fast -> 93.47 Mbps
Проверка между двумя Linux серверами с помощью iperf
# yum -y install epel-release # yum update # yum install iperf
На первом сервере:
# iperf -s
На втором сервере:
