Unixbench Installation and Use

Unixbench is a tool used to test the performance of unix systems and is also a common benchmark. The purpose of this test is to provide a basic performance indicator for Unix-like systems, many tests are used in different aspects of system performance. These tests result in an exponential value (such as 520 ), this value is the exponential value obtained by comparing the test result of the test system with the test result of a baseline system, which is easier to get reference value than the original value, the exponent values obtained from all tests in the test set are combined to obtain the exponent values of the entire system. Because in 1995, the baseline system was "George", a workstation: SPARCstation 20‐61,128 mb ram, Solaris2.3, which was set to 10, if the final result score of a system is 520, it means that the system runs 52 times faster than the baseline system.

1. Installation

Unixbench-5.1.2.tar.gz: http://soft.vpser.net/test/unixbench/

Tar-xzvf unixbench-5.1.2.tar.gz

Cd Unixbench-5.1.2

Read the README file and find out that if you do not need to perform a graphic test or do not test it on the graphical interface, comment out GRAPHICS_TEST = defined in the Makefile file. Mine is in 46 rows.
