VPS, independent server performance test: system information, upload/download bandwidth, hard disk I/O, UnixBench, ping, packet loss test, native IP, etc.

Only supported on Linux VPS or virtual hosts that support SSH. For quick tests, please see: One-click test scripts for server/VPS configuration, network speed, bandwidth, IO, performance, etc. under Linux

1. System information, bandwidth, I/O test
a. This tests domestic and international speeds:

 wget -qO- --no-check-certificate https://zhujiwiki.com/wp-content/uploads/2018/07/superbench.sh | bash

b. This content is comprehensive

 wget https://zhujiwiki.com/wp-content/uploads/vps-test/test.sh -N --no-check-certificate && bash test.sh

The above does not include UnixBench, the following includes UnixBench (test performance, very slow)

 wget https://zhujiwiki.com/wp-content/uploads/vps-test/test.sh -N --no-check-certificate && bash test.sh a

This script comes from: https://www.94ish.me/1752.html, the host encyclopedia updates nodes from time to time.

2. Upload/download bandwidth test

 wget https://zhujiwiki.com/wp-content/uploads/2017/10/speedtest.py --no-check-certificate python speedtest.py

3. Domestic access speed
a. http://www.webkaka.com/Ping.aspx
b. https://www.ipip.net/ping.php
c. http://www.17ce.com/

4. Hard disk I/O performance test
dd bs=64k count=4k if=/dev/zero of=test is the least valuable reference. Many junk VPSs use this.
dd bs=64k count=4k if=/dev/zero of=test; sync is not very strict
dd bs=64k count=4k if=/dev/zero of=test conv=fdatasync Foreign standards, not very strict
dd bs=64k count=4k if=/dev/zero of=test oflag=dsync Domestic standard, strict, and of reference value

To explain, the first one is the least valuable for reference and the last one may be 400 times more valuable than the last one. Some bad hosts will use it to boast about how awesome the host's I/O is.
If the last one is over 10M, you can build the site normally, but if it is over 50M, it will be invincible. The most strict one is also the most popular one among domestic enthusiasts.

Or the simplest one:

 dd if=/dev/zero of=test bs=64k count=4k oflag=dsync執行命令以后，系統會自動創建一個268M的文件一般來說10M左右對VPS的一般應用無影響。10M以上性能可觀。10M以下表示硬盤壓力有點大，1M以下……

The above is a normal HDD hard drive, and the following is an SSD hard drive test:

 yum install hdparm -y fdisk -l hdparm -T /dev/sda

5. UnixBench score of performance test <br /> After running for 10-30 minutes (depending on the number of CPU cores and the computing time), the score is obtained. The higher the better.

 wget --no-check-certificate https://zhujiwiki.com/wp-content/uploads/2018/07/unixbench.sh chmod +x unixbench.sh ./unixbench.sh

6. Packet loss test <br /> Use ATKKPING software to test the packet loss of local access.
Software download: ATKKPING.zip

7. Outbound route tracking

8. Backhaul Route Tracing

 wget https://zhujiwiki.com/wp-content/uploads/2017/12/besttrace4linux.zip unzip besttrace4linux.zip chmod +x besttrace ./besttrace -q 1 IP（這個IP換成-移動-218.205.152.14、聯通-220.196.42.133、電信-121.11.69.135）

If an error occurs, install traceroute.

9. Youtube speed test <br /> After installing SS, browse to https://www.youtube.com/watch?v=qO6-1u0wfPk, select 4K or 8K, and right-click to check the speed

10. Independent server hard disk usage time
Under centos:

 yum install smartmontools -y
service smartd start ; chkconfig smartd on
smartctl -a /dev/sda

11. Check whether it is a native IP
