Test script bench.sh (for network and IO tests of various Linux distributions)

 After several versions of iterations, the one-key test script bench.sh is almost applicable to the network and IO tests of various Linux distributions.

And display the test results in a more beautiful way.

Summarize the features of bench.sh:

1. Display various system information;
2. Test points taken from Speedtest data centers in many parts of the world, and the network test is relatively comprehensive;
3. Support IPv6 download speed measurement;
4. IO test (write 1GB data sequentially) three times, and display the average value.

Combined with the  unixbench.sh  script test, you can fully test the performance of the VPS.

How to use:
Command 1:

wget -qO-bench.sh | bash 

or

curl -Lso-bench.sh | bash 

Command 2:

wget -qO-86.re /bench.sh | bash _ _ 

or

curl -so-86.re /bench.sh | bash _ _ 

Note:
bench.sh is both the script name and the domain name. So don't suspect that I wrote it wrong or you read it wrong.

update log

Updated on February 22, 2022:
1. Added the judgment of whether the CPU supports AES-NI and VM-x/AMD-V;
2. Improved the algorithm for calculating hard disk space;
3. Improved the algorithm for calculating RAM and Swap;
4. Improve the time stamp display method and add time zone display;

Updated on January 1, 2022:
1. Optimized the script logic and beautified the display;
2. Upgraded the version of speedtest-cli to 1.1.1;
3. Supported arm64 (aarch64) and armv7l (armhf) architectures, as shown in the figure below;
・arm64 (aarch64)

・armv7l (armhf)

4. Optimize the speed test server list provided by Speedtest. Among them, the node information of Shanghai, Nanjing and Guangzhou in China is as follows

26352 ) China Telecom JiangSu 5G ( Nanjing, China )< font >< /font > 
27594 ) ChinaTelecom 5G ( Guangzhou, China ) 

・x86_64

Updated on July 29, 2020:
1. Modification: Speedtest is provided by Speedtest, which distinguishes between upload and download, which is more practical;
2. Added: TCP Congestion Control; virtualization method; IP information, etc.

The figure below shows my  Vultr  evaluation data:

Update on January 07, 2018:
Modification: The color of the displayed information is divided into categories to make it easier to distinguish.

The figure below shows the evaluation data of my KS3C 100M dedicated server:

Updated on November 24, 2016:
Added: display hard disk information; advance the location of the IO speed test, and put the network download speed test at the end.

As follows:

Put some test pictures at the end.

Linux performance test UnixBench one-click script

 

UnixBench is a performance testing tool for unix-like (Unix, BSD, Linux) systems, an open source tool, which is widely used to test the performance of linux system hosts. The main test items of Unixbench include: system call, read and write, process, graphical test, 2D, 3D, pipeline, operation, C library and other system benchmark performance to provide test data.

The latest version of UnixBench5.1.3 includes system and graphic tests. If you need to test graphics, you need to modify the Makefile, do not comment out "GRAPHIC_TESTS = defined", and the system needs to provide the x11perf command gl_glibs library.
The script below uses the latest version of UnixBench 5.1.3 to test, annotated the test items about graphics (most VPSs do not have a graphics card or an integrated display, so there is no need to test the graphics performance), after running for 10-30 minutes (according to the CPU core Quantity, operation time varies) to get a score, the higher the better.

testing method:

wget --no-check-certificate https://github.com/teddysun/across/raw/master/unixbench.sh
chmod +x unixbench.sh
./unixbench.sh _

Test item:
Dhrystone 2 using register variables
This item is used to test string handling, because there is no floating-point operation, it is deeply involved in software and hardware design (hardware and software design), compilation and linking (compiler and linker options), code optimization (code Optimazaton), the 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 integer and floating-point mathematical operations, array access, conditional branch (conditional branch) 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, like some other commands like it.

File copy
tests the rate at which data is transferred 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 the specified time (default is 10s).

Pipe Throughput
(pipe) is the simplest way to communicate between processes. Pipe throughput here refers to the number of times a process can write 512 bytes of data to a pipe in one second and then read it back. It should be noted that pipe throughtput has no corresponding real existence in actual programming.

Pipe-based Context Switching
This tests the number of times two processes (per second) exchange an ever-increasing integer through a pipe. This point is very similar to some applications in real programming. This test program first creates a sub-process, and then performs two-way pipeline transmission with this sub-process.

Process Creation
tests the number of times a process can create a child process and then withdraw 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, the focus on memory bandwidth. In general, this test is used to compare different implementations of the operating system process creation system call.

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 with a small program that repeatedly calls the getpid function.

Shell Scripts
tests the number of times a process can concurrently start n copies of a shell script within one second, and n generally takes the value of 1, 2, 4, and 8. (I take 1, 8 when testing). This script performs a series of transformations on a data file.

The following is the running score of a 512MB, 2-core, OpenVZ VPS of mine:
