Parameter description:

-- help displays help information

-- version displays software version information

-t secs:

-- timeout secs specifies how many seconds to run

-- backoff usecs waits for usecs microseconds to start running

-c forks:

-- cpu forks generates multiple CPU processes that handle the sqrt () function

-m forks

-- vm forks: generates multiple processes that handle the malloc () memory allocation function, followed by the number of processes

-I forks

-- io forks: generates multiple disk Icano processes that handle the sync () function

-- vm-bytes bytes: specifies the number of byte in memory. The default value is 1.

-- vm-hang: indicates how long the memory allocated by malloc will be released after free ()

-d:

-- hdd: write process, write to a fixed size, and write to the current directory through the mkstemp () function

-- hdd-bytes bytes: specifies the number of byte to write. Default is 1G.

-- hdd-noclean: do not unlink files written to random ascii data, the files written will not be deleted and will remain in the hard disk space.

Extraction code: hdml

Installation method: rpm-ivh * .rpm-- force

1. Test CPU load

Enter the command: stress-c 4

Add 4 cpu processes to deal with the sqrt () function to increase the CPU load of the system

2. Memory test

Enter the command: stress-m 50-- vm 500

3. Disk IBO test

Press memory and IO simultaneously

Enter the command: stress-d 1-hdd-bytes 3G

Add 1 new write process to write 3G file blocks each time
