High CPU load after 2.6.0 update

gtenorio

Hi,

After updating from 2.5.2 to 2.6.0, pfsense is experiencing a very high CPU load. I am not able to access the web gui or ssh.

I did a restart and noticed around 20% usage on interrupts.

Hardware? Installed packages? Running services?
Board - HDD/SSD - CPU - RAM?
Internet connection speed?

Would you be so friendly and tell us more about your used
hardware, running services and/or installed packages please.

Are you using PPPoE?
Since version 2.6, pfSense will be able to transport
the entire WAN load over much more then one queue.
So if the CPU is sorted with much cores and/or threats
it can be a really good chance to get a fast as can WAN port / throughput.

If you are running or using PPPoE you will be nailed
to one CPU core and one queue! So if you now
having much more to do for the CPU, it can be
pointed to that circumstance told above
(more queues = more throughput = more CPU
load or tasks)

7 x 1Gbps down/100Mbps up fiber
1 x 50Mbps leased line fiber

And with that much WAN ports, the entire amount of queues can be short and fast increasing once more
again and also stress the CPU once more as I see it.
