Cholmod is working fine for me. I have tried other packages in the past such as MUMPS and SuperLU and found them to be slower. Actually a lot slower - like 2x to 4x slower. I was just wondering if there were newer packages that would be worth trying i.e. that might have even better performance than cholmod. Sounds like not.
