[petsc-users] Overhead in snes function calls

[Adolfo Rodriguez]

I am porting a non-linear solution problem implemented explicitly to an
snes implementation. Everything seems to be working fine, except for the
fact that function calls done from snes to my jacobian and residual
construction subroutines are slower than the regular direct call to the
same subroutines (I hope this is clear). I wonder if somebody have observed
this behavior and found a solution.

Regards,

Adolfo
