@SteveITS Adaptive jumped between 2.2, 2.4 and 2.6Ghz, keeping around the same temps as with PowerD off at 2.4Ghz. Its why I figured just leaving PowerD off might make more sense, the difference in power consumption on a 15W CPU is immeasurably low.
I don't think it made more than a watt or two difference when I used a generic PC with a 45W CPU, FreeBSD I suspect is tuned for performance more than power saving as Linux in comparison idled at about half the power consumption of pfSense. Though obviously were on a much newer kernel now.
@stephenw10 Its survived a couple of years already.
I've actually ordered a newer model with the 8250U as I'm curious how the lower clocks but more threads would scale with my setup as I'm currently load balancing over three WANs and three VPN clients.
I suspect it will bottleneck on OpenVPN once I move to Gigabit some time this/next year, but it will give me a chance to see if the CPU thermal transfer can be improved on the 7200U in the meantime.
Was actually impressed as I set it to minimum accidentally while figuring this out and at 400Mhz two WANs were still happily pushing 60Mbit each over OpenVPN, but the third WAN speed throttled. That kinda makes sense on a dual-core I guess, the higher latency link being the one that throttled back.
