1,000,000 observations in a dataset. Then you would end up calculating 2,000,000,000 terms for each step. If you multiply it with your number of iterations (take 1,000), then it will make 2,000,000,000,000 calculations. This makes gradient descent slow for relatively large data. Stochastic Gradient
