The most interesting observation seems to be that the results are
largely inconsistent (look at 'atom', for example). Even wheel-
sieve1, where our numbers go in the same direction, varies between
+10% and +22.7%. My numbers are from an older HEAD (as I had nofib
handy there), but I'm still wondering where this difference comes
from. Is it just that different processors are more or less
sensible to TNTC?
There is a video of a Google Tech Talk on the topic of how
inconsistent and confusing benchmark results arise.

Well worth investing 50 minutes of your time, if you ever do any kind
of performance benchmarking. Warning: you may be shocked at how easy
it is for unforeseen and uncontrolled factors to obfuscate your
measurements, to the point of indicating a gain instead of a loss, and
vice versa. Something as random as library link-order can flip the
sign...
