### Performance

In the current implementation, M31 and BabyBear has equivalent performance for the standalone field.
In the current implementation, M31 and BabyBear have equivalent performance for the standalone field.
The overhead for field extension is slightly different due to the extension polynomial.

The BabyBear4's multiplication overhead slightly goes down from 13594 to 13576 because we switched the extension polynomial
into x^4 + 11 (the one used by RISC Zero) from x^4 - 11 (the one used by Plonky3) as the former is more heavily used in
production. This slightly reduces the cost because multiplication by -11 can be done slightly cheaper than multiplication
by 11.
