Comment (by tom):

 I was worried that we might be exposing hardware information via this.

 I compared the numbers I got on my x64 Nightly running on a Surface Go and
 got the same results as those of Thorin's Win7/Win10 x64 on x64 here:
 https://github.com/ghacksuserjs/TorZillaPrint/issues/30 .  I'm reasonably
 convinced this means that hardware is not a factor in these values, and it
 comes down to OS and related libraries.
