Not necessarily. A very rough rule of thumb is keep those numbers under 2.0 most of the time. What you need to worry about more is a few individual processes eating lots of cpu.
prstat is your friend for this. What those numbers mean is this:
Assume you are going to the bank to do a transaction. When you get there, how many people are in front of you in the the line? So if you have to keep coming back to the line then how long, on average do you have to wait to get service. As those numbers grow it means you wait longer and longer for service. On systems running databases the db frequently uses a lot of resources, comapred with user processes, but it is designed to optimize the use of those resources. So it is common to see some cpu usage like the ones you have.
What exact performance problem do you have?

Thanks Jim.
I had upgraded total RAM from 1Gb to 5Gb and, iirc, load did not decrease (perhaps it even increased). However, there is plenty of free RAM now and it doesn't swap like it used to; ssh seems more responsive. I haven't noticed performance problem really, but we plan to expand oracle database and need to know if hardware can handle it.
@SunSolars_admin, you are confusing the system load average, which relates to the process run queue length in the last 1, 5 and 15 minutes with the percentage the CPU is running system (kernel) code.
Here is a useful SSL (HTTPS) application for anyone with a remote Linux server they want to keep an eye on using Blynk and the NodeMCU ESP8266. This little app also works (have tested as well) on the WeMos D1 ESP8266 Arduino board.
The NodeMCU setup could not be easier, just find a... (8 Replies)
`/proc/loadavg` give me three indicators of how much work
the system has done during the last 1, 5 & 15 minutes.
How can i get a list of load averages
that each averaged over the last minute for 10 minutes? (2 Replies)
I know that Sun make s a version of Solaris for Sparc platforms and also an x86 (Intel/AMD) release of Solaris. Can an application that runs on Solaris/Sparc also run on a PC running the x86 release of Solaris? Would a different release be required or any re-compling of the application?

hi all
need your help.
I am wrting a script that will load data into the table.
then on another load will append the data into the existing table.

Hi,
I am seeing very high kernel usage and very high load averages on my system (Although we are not loading much data to our database). Here is the output of top...does anyone know what i should be looking at?
Thanks,
