Benchmarking R, why sort() is so slow?
...n is considered for each serie (best and worst scores eliminated). The tests are scaled to be done in approx. 1 sec on the reference computer with the reference software being Matlab 6.0 R12 (column C). Serie I: Matrix calculation 1 = Creation, transposition, deformation of a 1200x1200 matrix, 2 = 1250x1250 normal distributed random matrix ^1000, 3 = Sorting of 1,100,000 random values, 4 = 550x550 cross-product matrix (b = a' * a), 5 = Linear regression over a 700x700 matrix (b = a \ b') Serie II: Preprogrammed matrix functions 6 = FFT over 900,000 random values, 7 = Eigenvalues of a 220x220...
