I am solving a sparse linear system Ku = B using alglib::sparsesolve in C++, the matrix is around 1e4x1e4 in size and 99.9% empty. However the computation time on my personal computer is around 1 minute, which looks very high for such matrix (I am running in sequential with commercial version of Alglib, the matrix is in CSR format). I was wondering if this computation time was normal or if I misunderstood something.
int nLen = B.length()
