PFsense SLow and High CPU
-
Well, you have a shitton of php processes running for god knows what reason.
- Restart webConfigurator from console
- Restart PHP-FPM from console
- Limit the GUI processes if not done yet (System - Advanced - Max Processes).
Also look at the dashboard whether the GW monitor does not show some totally BS figured, like 109% packet loss. If it does, kill apinger.

- Restart webConfigurator from console
Whats the right command to do it?
- Restart PHP-FPM from console
Whats the right command to do it?
- Limit the GUI processes if not done yet (System - Advanced - Max Processes).
It's set to 2, do i have to change it ?

The right command is to use the fine console menu that's there (both via SSH and on physical console).

Disable the Captive portal thing.

Do you thin kthe Platform is not powerfull enough ? ( we have 100-150 users)
-
also might try
sysctl dev.em.0.debug=1 ```from console -
karlzre - Apparently not in your case when idiots/broken mobile shit keeps hammering the CP over and over again. (Other than that, you told us exactly NOTHING about your "platform"). And yeah, there's also something very broken about the NICs. Did you enable some nonsense like polling there?

I have a bit more power behind my box and Ive run into the same thing.. Is powerd on minimum capable of causing this issue?
my machine gets loaded up with 60mbits of torrent/netflix traffic (that is my connection speed) from time to time and I see that [kernel{em0 taskq}] and [intr{swi5: fast taskq}] tasks taking up the majority of the available CPU.. Polling is turned off..
This machine as built from spare parts that I had laying around is it possible that im just running into a limitation with the hardware?

You need to fiddle with whatever settings are available there. People here mentioned boxes where CPU is never run at full freq unless powerd is enabled somehow. Sure if set @minimum, that's a good candidate.

You may also want to look at https://forum.pfsense.org/index.php?topic=59028.0 to remove those messages from the log and help cut down the noise. Looks like they may not mean anything.

Interestingly enough, I switched it to adaptive and the overall load on the machine has lowered a HUGE amount. Lets say from 6.0 to under 0.7-0.5.. Kind of ironic that the feature meant to save energy is actually causing an increase… (in this situation)
Seriously, Turn on the profile "minimum" and max out your connection, your load will raise slowly.. turn it to Adaptive and watch it lower almost immediately. "[kernel{em0 taskq}]" is the task using all the cpu..

You're misunderstanding what're being reported. Load is relative. If your CPU is running at 100mhz, then it's not hard to reach 75% usage. The reason "load" is high when using minimum is because the CPU is being down-clocked, you are saving power.
