Test Linux System Performance using Command Line Tools Part-1


Uptime Command display results include server has been running for how long, how many users log on the server performance and overall assessment load average. Load average values were recorded in the last 1 minute, 5 minutes and 15 minutes intervals of the load, load average is not a percentage, but in the queue waiting for the process of implementation of the number. If the process requires that the CPU time is blocked (meaning the CPU did not have time to deal with it), load average value will increase. On the other hand, if each process can get immediate access to CPU time, this value will decrease.

UP kernel load average under the optimal value is 1, indicating that each process can be CPU processing immediately, of course, lower is not a problem, only shows part of a waste of resources. However, this value between different systems are different, for example, a single-CPU workstation, load average of 1 or 2 are acceptable, but in a multi-CPU systems this value should be d…
