in thread Help with Double Double Quotes regular expression

I noticed that your sample $s is a non-matching one.

Did you take that on purpose to emphasise on cutting off backtracking in the failing case?

When I balance the (double)quotes in $s by adding one in last position (directly before the closing parentheses of q,) "straight" seems to have a slight edge over "cut"

Rate cut straight cut 110876/s -- -13% straight 127147/s 15% --
I got similar figures as you for your original $s
