Hi all,
This equipment is new and I'm experiencing too slowly when I connect via SSH, access privileged mode, or typing commands like "show run" for example.
At first glance there appears to be excessive consumption (CPU utilization for five seconds: 2% 1% one minute: 3% five minutes: 2%), but I am very worried and wanted to find a solution.
Does anyone know which may be due, and how could I fix it?
Thanks

Your cpu is 0-1%. The processes look normal and low.
I don't understand what your concern is.

~3% CPU is very low. You should not worry.
When you connect with ssh the device will generate RSA DH numbers and it is normal to spike your CPU a little.
But still 1-3% is very very low and you should not consider it as high CPU.
To check what processes take up your CPU do "sh process" twice with 30 sec difference and do the diff on the processes to see which one took up most of the cpu during the 30seconds.

Hi, I'm sorry for not having explained:
what I mean is if you think that the slowness is related to the consumption of CPU or anything else (bad configuration, etc.) related to this other thread.

Thanks for your help

I don't think it is the CPU.
Please check the interface that you are ssh-ing for duplex mismatch with what it connects, and errors.
Also check for packet loss in the path to your computer.
Also if you are doing command authorization check if the ASA has connectivity issues to the ACS server.
These are what I would suspect.
