# sparse function is intrisically slow?

I am building the sparse matrix using the function sparse(I,J,V,N,N)

I, J and V are already a column vector. I checked previous questions, it seems already being the best way. But, it takes extreamely long time if the size goes to 1E5.

Any way out? Thanks!
