High cpu on 2100 after upgrade to RC from Beta

[stephenw10]

We saw it in earlier beta snapshots but not since.

How many DHCP clients do you have?

Are you seeing that 30% CPU usage with the webgui open or at the CLI?

@stephenw10 I have under 30 dhcp clients all ipv4. Yes, on the UI screen it does jump so I looked at the long term average: I do not see long term load average of under 20% with the RC candidate. With 24.03 release, I do see under 20% long term load average fyi.

@applesalwaysred how long is your lease duration?

[applesalwaysred]

@cmcdonald 86400s.

In the Status > Monitoring graphs?

[applesalwaysred]

@stephenw10 sorry, I meant I have not seen under 20% cpu usage (long term) on the RC build compared to the 24.03 release where it is common.

[stephenw10]

Right I'm just wondering where you are checking that?

Since I don't see that on 2100s here:

[applesalwaysred]

@stephenw10 load averages on system diagnostics (at thread top) & dashboard with the 3 state state load averages. Not the current cpu usage. What happens when you add in kea with 'Enable DNS registration' and 'Enable early DNS registration' ?

[stephenw10]

So loads above 0.4 on the longest average?

[applesalwaysred]

@stephenw10 ~.36

[stephenw10]

Do you have the top output from that after it's been stable for some time?

[applesalwaysred]

@stephenw10

[stephenw10]

Hmm, those php processes are the webgui displaying that. I see similar loads here.

Try running top -aSH at the CLI without the webgui open at all.

[applesalwaysred]

@stephenw10 cli with kea no options (nice).

Here is cli with those kea options enabled:

[stephenw10]

Hmm, OK. Significant.
