Host cpu performance

openssl speed md5
Measure the cpu performance: In-case if the cpu is thermal throttling then you can find it using this command. Check the first line of the output. Example: Doing md5 for 3s on 16 size blocks: 11406892 md5's in 2.98s ? #(When cpu is not throttling) Doing md5 for 3s on 16 size blocks: 110692 md5's in 2.98s ?? #(When cpu is thermal throttling) Practical use case: Once we had cooling outage in data center which caused thermal throttling in some of the worker nodes. We used this tool to prove that some servers are not performing well because of the cpu thermal throttling.
Sample Output
Doing md5 for 3s on 16 size blocks: 11406892 md5's in 2.98s
Doing md5 for 3s on 64 size blocks: 8479926 md5's in 2.99s
Doing md5 for 3s on 256 size blocks: 4800618 md5's in 2.99s
Doing md5 for 3s on 1024 size blocks: 1719000 md5's in 2.98s
Doing md5 for 3s on 8192 size blocks: 249448 md5's in 2.99s
