安裝工具 iperf3

centos

yum install https://iperf.fr/download/fedora/iperf3-3.1.3-1.fc24.x86_64.rpm -y

debian

wget https://iperf.fr/download/ubuntu/iperf3_3.1.3-1_amd64.deb

測試網路頻寬

啟動 server 端

iperf3 -s

啟動 client 端 (測試 100G 雙向)

iperf3 -c <server ip> -n 100G -R -i 10 -P 10 && iperf3 -c <server ip> -n 100G -i 10 -P 10

curl -s https://packagecloud.io/install/repositories/akopytov/sysbench/script.rpm.sh | sudo bash
sudo yum -y install sysbench

測試 CPU 效能

執行測試 30s 算質數數量

sysbench --threads=1 --time=60 cpu  run

結果以 total number of events 作為性能基準

root@pve1:/vm-storage# sysbench --threads=1 cpu --cpu-max-prime=1000 --time=30 run
sysbench 1.0.20 (using bundled LuaJIT 2.1.0-beta2)

Running the test with following options:
Number of threads: 1
Initializing random number generator from current time


Prime numbers limit: 1000

Initializing worker threads...
