New to pfsense, gui is slow and constant 25% cpu load?

[yannie]

Hey all,

I'm brand new to pfsense, but enjoying it so far… I've noticed that now that I'm all set up I'm getting a constant 25% cpu usage (AMD FT3 Kabini A4-5000 Quad-Core APU) and the web gui doesn't seem to be as snappy as in youtube setup videos I've watched...

I'm not sure if this is helpful, but I found this:

Snort is notorious for CPU and RealTek is a horrible brand. I would start with disabling snort to see if that fixes the snappiness.

@Harvy66:

+1…  regarding snort.

For what concerns Realtek, I do share but doubt it has visible impact, at least until there is a significant network load.
Although I try to deploy Intel whenever this is feasible, I still have some RealTek interfaces and don't face performance issues due to this, as far as I know  ;)

RealTek is hit and miss. Love it when it works, loath it when it doesn't.

Everyone,

Thank you for your responses.  I have completely removed Snort (uninstalled the package) to ensure that it's not being used.  And I'm still showing a constant 25% load… note that the load is never reported as anything other than 25%, not sure if that helps anyone.

As for the NIC, I am just temporally using the onboard nic until another pcie x1 single intel nic arrives in a couple of days.

Post your System Activity again. It'll tell you exactly what is using your CPU.
