petsci and csparse
 

Hi,
My work is on implicit methods for Euler equations which involves inversion of large sparse matrices. I have been able to solve 2-D cases by using CSPARSE available freely. Recently I tried to convert all codes to PetSci but found that it takes much longer time(in the order of 100s) for 1d code to converge.
I would like to knnow if this is the trend.
Thanks in advance.
