Matrix Construction Functions Seem Very Slow

Hello everyone, I am having problems using matrix constructions to augment/stack matrices together using Maple 9.0. The types of matrices I am combining are not huge, perhaps only 4 256x256 matrics into 1 512x512 matrix, although they do contain complex numbers that may be beyond hardware precision and therefore using arbitrary software precision. My main issue is with the speed this takes. If I use the old "augment" or "stackmatrix" constructors from the "linalg" package then this takes about 15 secs on my pc (1.4GHz 512MB) which seems unnecessarily long to me in the first place. Furthermore, if I use the new constructors from the "LinearAlgebra" package ("
complex package
