SNES isn't meant to solve tiny independent systems. (It's just high
overhead for that purpose.) You can solve many such instances together
by creating a residual
Hi Matthew,

Dear Petsc developers,
in my application I have to solve millions of linear and non-linear
systems with small matrices (2x2, 3x3,..., 10x10).
I consider them as dense, and use SNES with KSP method PREONLY, and LU
preconditioner.
I found that when KSPSolve is called only 25% of time is spend
