That means in the intervening ~4 months (from 21 October to last week), there
could be some changes that made things better substantially. Unfortunately,
because the JAX RS integration was not reverted when the performance
degradation was first reported, it is difficult to exactly pin-point as to
which commit(s) made the performance better now. Does anyone have a
clue/guesses?

That means in the intervening 4-5 months, there are some changes that made
things better substantially. Unfortunately, because the JAX RS integration was
not reverted when the performance degradation was first reported, we can't
exactly pin-point as to which commit(s) made the performance better now. Does
anyone have a clue/guesses?
