Title: Pfsense - Adaptive vs Hiadaptive power setting
Post by: Jon21 on October 29, 2019, 05:01:21 PM

In Pfsense, which power setting should I use when PowerD is enabled? Not really noticed much difference between them, other than I get a intermittent annoying coil whine type noise if I use Hiadaptive. Don't seem to get it with Adaptive. Wonder if it is because Adaptive seems to step down the CPU frequency more than Hiadaptive?

They both the same in that they both allow low idle clocks, and both enable turbo clocks to be used.  Hiadaptive however will ramp up quicker when is load and take longer to drop clocks under idle conditions.  So its more responsive.

Power management on FreeBSD in general is garbage, it doesn't idle nearly as low as Linux which is one of the drawbacks of pfSense.

Actual Internet response "feels" faster in pfSense over OpenWRT though, so was worth it.

Coil whine is why I moved the router to the opposite end of the room to the modems. ;)

I think that's mainly down to the poor cstate's code, powerd manages pstate's tho, powerd seems to do its job fine thankfully.

Thanks for the replies, I've kept it on Adaptive for now.

I switched mine to hiadaptive, temps have increased but it also seems more responsive.
