[R] Fisher Scoring v/s Coordinate Descent for MLE in R

R base function glm() uses Fishers Scoring for MLE, while the glmnet uses the coordinate descent method to solve the same equation ? Coordinate descent is more time efficient than Fisher Scoring as fisher scoring calculates the second order derivative matrix and some other matrix operation which
