There are too many VPS hosts these days, and many "second-hand" VPSs have become rampant, making it difficult to tell whether they are real or fake. If you want to buy a certain VPS host, you usually have to look at the evaluation data of this VPS host first. In the past, when sharing VPS hosts, I would give VPS performance and speed test reports. This time I will sort out the relevant test tools.
Firstly, I will make a memo for myself, so that when I test VPS in the future, I will not have to go to Baidu to ask for commands. Secondly, I will give some help to my friends who have never used it. These tools are common to many webmaster friends. What is the value of the VPS host I purchased? Whether it is worth the price or not, you will know once you test it with these tools, and the operation is simple and only requires a few commands to complete.
It should be reminded that regarding the IO read and write speed test, based on past experience, the IO read and write speeds of Google cloud servers, Amazon servers, etc. are relatively low, while SSDs perform well in IO. In addition, the speed of foreign VPS hosts depends largely on the quality of the line, and the test speeds at night and during the day will be quite different.

1. VPS speed test tool
Online testing tool. Using online testing tools can easily obtain the server's response time. This method is particularly effective for foreign VPS. The following is a collection of useful online website speed testing tool websites:
http://ping. Which kind of food to eat.com/
HTTP://oooooo.IP IP.net/ping.PHP
HTTPS://wuwuwu.17test.com/
HTTP://wuwuwu.Webkaka.com/
HTTP://test.cloud.360.abilities/
Each of these online speed testing tools has its own advantages and disadvantages. It is recommended to use ipip.net to test the server IP and route tracing, 17ce.com to test the web page loading speed, and ping.chinaz.com to test the ping values from different places in the country.
Local testing software. It is recommended to use WinMTR, which is a convenient and easy-to-use route tracing tool. This software can help users directly check the response time and packet loss rate of each node, and is very suitable for customers under Windows to do route tracing and PING testing.
Download address: https://www.ucblog.net/wzfou/WinMTR-CN-IP.zip
Project homepage: https://github.com/oott123/WinMTR
Version with map: https://cdn.ipip.net/17mon/besttrace.exe
Enable WinMTR and click to update the IP address.
Enter the domain name or server IP you want to track, and then you can see the nodes the data packet passes through and packet loss, etc. It also supports exporting text.
related parameters are described as follows:
Hostname: Each host IP or name that needs to be passed to the destination server
Nr: The number of nodes passed through; Baidu in the above picture is an example: a total of 10 nodes are passed through, the first of which is the exit router
Loss% : The percentage of ping packet reply failures; use this to determine which node (line) is faulty, whether it is the computer room where the server is located or the international routing trunk line
Sent: the number of transmitted data packets
Recv: successfully received data Number of packets
Best: Minimum response time
Avrg: Average response time
Worst: Maximum response time
Last: Response time of the last packet
PS: Updated on September 12, 2017, Superspeed.sh one-click test server to domestic speed script:
wget https://raw.githubusercontent.com/oooldking/script/master/superspeed.sh
chmod +x superspeed.sh
./superspeed.sh2. VPS performance testing tools
Manual detection command. Use the command directly: cat /proc/cpuinfo or lscpu, and you can see the CPU configuration of the VPS you are using.
For the detected CPU, you can also enter this website: http://www.cpubenchmark.net/cpu_list.php to see how the CPU performance ranks, at least to give yourself an idea.
Another manual command to test disk IO:
dd if=/dev/zero of=test bs=64k count=4k oflag=dsync Manual command to test VPS network:
wget http://cachefly.cachefly.net/100mb.testOne-click detection script. Here is a one-click test for VPS CPU, memory, load, IO reading and writing, computer room bandwidth, etc.

VPS performance comprehensive benchmarking tool. UnixBench is a performance testing tool under Unix-like systems (Unix, BSD, Linux). It is an open source tool and is widely used to test the performance of Linux system hosts. The main test items of Unixbench include: system calls, reading and writing, processes, graphical tests, 2D, 3D, pipelines, operations, C libraries and other system benchmark performance to provide test data. The command is as follows:
wget --no-check-certificate https://github.com/teddysun/across/raw/master/unixbench.sh
chmod +x unixbench.sh
./unixbench.shThe test project description is as follows:
Dhrystone 2 using register variables
This item is used to test string handling. Because there are no floating point operations, it is very popular in hardware and software design, compiler and linker options. ), code optimization (code optimazaton), impact on memory cache (cache memory), wait states (wait states), and integer data types (integer data types).Double-Precision Whetstone
This one tests the speed and efficiency of floating point operations. This test consists of several modules, each of which includes a set of operations for scientific computing. A wide range of C functions: sin, cos, sqrt, exp, log are used for mathematical operations on integers and floating point numbers, array access, conditional branches, and program calls. This test tests both integer and floating point arithmetic operations.Execl Throughput
This test examines the number of execl system calls that can be executed per second. The execl system call is a member of the exec family of functions. It is a front-end to the execve() function, along with several other similar commands.File copy
Tests the rate of data transfer from one file to another. Each test uses a different size buffer. This test for file read, write, and copy operations counts the number of file read, write, and copy operations within a specified time (default is 10s).Pipe Throughput
Pipe (pipe) is the simplest way to communicate between processes. Pipe throughtput here means that a process can write 512 bytes of data to a pipe in one second and then read it back. number of times. It should be noted that pipe throughput has no real counterpart in actual programming.Pipe-based Context Switching
This tests the number of times (per second) that two processes exchange a growing integer through a pipe. This is very similar to some applications in real programming. This test program first creates a child process, and then performs two-way pipe transmission with this child process.Process Creation
Tests the number of times a process can create a child process and then retract the child process per second (the child process must exit immediately). The focus of process creation is the creation and memory allocation of the new process process control block (process control block), that is, a sharp focus on memory bandwidth. Generally, this test is used to compare different implementations of this system call created by an operating system process.System Call Overhead
Tests the cost of entering and leaving the operating system kernel, that is, the cost of a system call. It does this using a small program that calls the getpid function repeatedly.Shell Scripts
Test the number of times a process can concurrently start n copies of a shell script within one second. n generally takes the value 1, 2, 4, or 8. (I took 1, 8 when testing). This script performs a series of transformation operations on a data file.
Depending on the performance of your VPS, it usually takes more than half an hour to get the running score results. The higher the score, the better the performance. (Click to enlarge)
Here is another VPS speed and performance comprehensive testing tool. You can use it to test the basic configuration of the VPS host, computer room bandwidth, ping value, IO performance, UnixBench scores, etc. with one click. The testing process takes a long time, so you need to wait patiently. .
#普通模式（测试机器配置， IO ，带宽和全国 ping 值）：
wget -N --no-check-certificate https://raw.githubusercontent.com/91yun/91yuntest/master/test_91yun.sh && bash test_91yun.sh
简单模式（测试机器配置， IO ，带宽和全国 ping 值）：
wget -N --no-check-certificate https://raw.githubusercontent.com/91yun/91yuntest/master/test_91yun.sh && bash test_91yun.sh s
完全模式（测试机器配置， IO ，带宽、全国 ping 值、unixbench跑分）：
wget -N --no-check-certificate https://raw.githubusercontent.com/91yun/91yuntest/master/test_91yun.sh && bash test_91yun.sh a3. VPS host authenticity detection
Detect VPS real memory. First use the command to check the real memory: free -m, then switch to the memory directory: cd /dev/shm, and then write the data. The mark count=100 means writing 100M. You can change it to the one marked by the host brand. The memory limit is a little bit:
dd if=/dev/zero of=./memtest bs=1M count=100
#注意完成后，执行删除：
rm ./memtestOnce an error occurs: dd: error writing ‘./memtest’: No space left on device, it means that the memory size is lower than the value we tested. You can continue to reduce the value until you get the real memory.
Detect VPS virtualization technology. The command is as follows:
wget -N --no-check-certificate https://raw.githubusercontent.com/91yun/code/master/vm_check.sh && bash vm_check.shThe test results will show whether it is KVM, Xen or OpenVZ.
Self-built speedtest test. This is suitable for VPS hosting providers to facilitate customers to test the download speed from the server to the user's local area.
Project homepage: https://github.com/adolfintel/speedtest
Modified version: https://www.ucblog.net/wzfou/speedtest-lite.zip
Upload the program to the server, and after the customer opens it, he can test the speed of the server by clicking on it.
4. Summary
UnixBench performance scores are greatly affected by versions. UnixBench currently has different versions, and many versions on the Internet have been manually modified. The results may be different due to different test projects. Remember to find a reference for comparison when testing.
IO read and write speed is greatly affected by the host machine. There are some overbooked servers. Due to the large number of users, the IO speed is very slow. Be careful of your "neighbors" like this. When using one-click script detection, if it is used in a domestic VPS, the network speed test will freeze.
