:aswan Unless there's something fishy with this new baseline, I want to mark this as WONTFIX.
To be honest, I don't really understand this, the patch in bug 1495638 should not have affected how this test is measured. Something is suspicious with the test generally though, baseline measurements for sessionrestore_no_auto_restore are higher than vanilla sessionrestore measurements, which makes no sense. In any case, I agree with marking it WONTFIX.
