Hi, i have installed OBSD on a small KVM based VPS [1]. The VPS dashboard provides knobs to enable/disable the following options (current setting in brackets)
- APIC (On) - ACPI (On) As this VPS have a miniscule load I would like to reduce its energy consumption to the minimum and because this I have started to think about the power management. Would it make sense to use obsdfreqd on a VPS? Could you give me any hint to make sure my VPS doesn't consume power unnecessarily? Is there any way to measure or estimate the power usage of a VPS? As you can see, i tried to use virtio based disk and network devices because emulating quirks of hardware may increase power consumption. Thank You!
