Hi, Libmesh Users I find the stiffness matrix assembling is very slow at the first time. But it is very quickly at the second time and laters for the same system. It needs 2 hours to assemble the stiffness matrix of the 3d stokes system with 15,000 dofs. How to speed up the process of assembling the system stiffness matrix at the first time? I find the similar question in the maillist. The title is "assembling a PetscMatrix".
