That's quite correct.  There are some 2.6 backports in the
severn kernel, but not nearly as many.  And quite a lot of
performance tuning went into taroon kernels.

In addition, later taroon kernels had debugging stuff like slab
poisoning turned off, whereas severn kernels have slab poisoning
still turned on.

So the severn kernel should get a bit faster in some cases when
we disable slab poisoning (scheduled for test3) but we wouldn't
expect it to perform equivalently to the taroon kernel, which
is developed under a very different regimen.
