There are still a couple of optimizations Not implemented:

[x] Disable bounds checks for access to coefficients
[x] Use @boundscheck to check the bounds of x
[ ] The evaluation of the partial derivatives with the evalpoly macro all have the same degree pattern. Currently we evaluate them one after the other, but if we do it parallel we should be able to get the FMA pipeline better filled

Another thing is that for the evaluation of the systems currently each polynomial is evaluated separately. We can use the @_inline_meta macro to inline the generated functions. If the compiler doesn’t give up on the amount of code generated it should eliminate multiple computations of the setup for the goertzel like evolution.
