Both Windows 11 systems are configured with the “High performance” power plan, as are the two Windows Server VMs. In hindsight, I should have included this detail explicitly in the original post instead of only alluding to it.

For others unfamiliar with Windows, according to https://learn.microsoft.com/en-us/windows-server/administrat... "High Performance" entails:
> Processors are always locked at the highest performance state (including "turbo" frequencies). All cores are unparked. Thermal output may be significant.
This isn’t specific to windows. This is also basically the same terminology Linux uses.
There's no mode spelled the same ("High Performance") - and I don't think Linuxes universally do this:
> Processors are always locked at the highest performance state (including "turbo" frequencies).
Unless performance state means something idiosyncratic in MS terminology.
Normally you'd want to let idle apply power saving measures including downclocking to donate some unused power envelope to busy cores, increasing overall performance.
But this varies across various Linux based platforms. For example on RHEL (https://docs.redhat.com/en/documentation/red_hat_enterprise_...):
"throughput-performance:
accelerator-performance: latency-performance: Here the latency-performance profile sounds most like the Windows Server mode (but differnet from throughput-performance).Even if you do that, there are firmware-level overrides that most laptops won't allow you to override. If you did, the laptop would melt.
You might be benchmarking the chassis fans more than the CPUs!
Agreed. Not to mention NVME SSD throttle pretty quickly due to heat too.
