top-performance
How we will evaluate the system performance and database performance using the below.
top - 10:35:10 up 127 days, 19:42, 1 user, load average: 0.46, 0.53, 0.72
Tasks: 329 total, 1 running, 325 sleeping, 0 stopped, 3 zombie

Yes slightwv
how to use "top" to help figure out performance issues
How we calculate.

How we calculate.
Sorry but "how" to use a tool is above a simple Q&A site like this.
In a nutshell, you can use top to look at what processes are using what resources.
If you see a slowdown in the system, top should tell you the most resource consuming processes. Then you need to figure out what those processes are doing but that is outside of what top does.
The man page will have all the available options and what they mean.

Good comment.
Maybe I'm not understanding what you are asking.
What do you mean "evaluate"?
Were you experiencing performance issues when you took that snapshot?
Are you wanting to know how to use "top" to help figure out performance issues?
