You deployed the new server and your code, but do you want to check how it will perform under a high CPU load? So here comes STRESS utility. It will create a load on the server so you can observe performance under stress. Let’s see some Stress Command Examples
Stress Utility is a workload generator tool designed to increase the load on the server so you can properly measure the performance of your application under high CPU, I/O, and disk stress.
Installing Stress Utility
On Centos servers, you can just run the command below.
$ yum install stress -y
On Ubuntu, it goes with
$ apt-get install stress
If you are on EC2, then you will have to do this as well
$ yum install amazon-linux-extras install epel -y
Now you spawn 8 workers on the stress utility to create load.
Let’s see the current load on the server.
$ uptime 04:12:18 up 182 days, 13:45, 1 user, load average: 3.27, 0.94, 0.36
Now, let’s run the stress command using the command below.
$ stress -c 8 & [1] 13255 $ stress: info: [13255] dispatching hogs: 8 cpu, 0 io, 0 vm, 0 hdd
Wait for a few seconds and see it has started generating load.
$ uptime 04:13:59 up 182 days, 13:47, 1 user, load average: 8.66, 3.45, 1.32
