there is a notable perf regression in many of the tests we cover
in one (or more) of these commits:

This show the percentage of difference of the Ir count between the two sha
for the different test:
select distinct test_name, round(((last_value(ir) over wnd -
first_value(ir) over wnd ) + 1.0)*100.0/first_value(ir) over wnd, 2) from
runs where  sha='bc9ff64c40a3e39b705f9fb141a63fc5c014b930' or
sha='39c8d40ddf85903d9ea2b81ae4ca924e91f89cb7' window wnd as ( partition by
test_name order by test_name,sha rows between UNBOUNDED PRECEDING AND
UNBOUNDED FOLLOWING) order by test_name;
