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 testing, please check: One-click test script for server/VPS configuration, network speed, bandwidth, IO, performance, etc. under Linux

1. System information, bandwidth, I/O test
a. This tests mainland China and international speed:

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 contain UnixBench, the following contains UnixBench (testing 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, and the nodes are updated 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. Mainland China 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 has the least reference value. Many junk VPS will 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 Mainland China standard, strict, with reference value

Explain, the first one has the least reference value and the last one may be 400 times different. Some bad hosts will use it to say how awesome the I/O of the host is.
If the last one exceeds 10M, the website can be built normally, but if it exceeds 50M, it will be invincible. The last one is very strict, and it is also the favorite one for people with fever in mainland China.

Or the simplest one:

dd if=/dev/zero of=test bs=64k count=4k oflag=dsync
After executing the command, the system will automatically create a 268M file
Generally speaking, about 10M has no impact on the general application of VPS. The performance above 10M is considerable. Below 10M means the hard disk pressure is a bit high, below 1M...

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

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

5. UnixBench scores for performance testing
After running for 10-30 minutes (depending on the number of CPU cores and calculation 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
Use ATKKPING software for testing to test the packet loss of local access.
Software download: ATKKPING.zip

7. Outbound route tracking
https://www.ipip.net/traceroute.php

8. Return route tracking

wget https://zhujiwiki.com/wp-content/uploads/2017/12/besttrace4linux.zip
unzip besttrace4linux.zip
chmod +x besttrace
./besttrace -q 1 IP (replace this IP with -China Mobile-218.205.152.14, China Unicom-220.196.42.133, China Telecom-121.11.69.135)

If an error occurs, please install traceroute.

9. Youtube speed test
After installing SS, browse https://www.youtube.com/watch?v=qO6-1u0wfPk, select 4K or 8K, right-click to view 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 the IP is native
