performance of bls12-381 #65

I just tested the bls12-381. To my surprise, the bls12-381 is much slower than bn254. I tested 1000 times ecc_mul, bn254 use 90ms, and bls12-381 use 900ms. Why? Maybe I made some mistakes(some optimize compile flags)?

sorry, I made a mistake. Should be 90 vs 380.

What CPU did you use? The rate of bls12-381 to bn254 is about less than 3. benchmark
