That's a diagonal and source only equation the exact solution of which is source/diagonal with a residual of 0 and no iterations so it didn't seem useful to print this information on the screen.

Thanks for your help! Just make sure I get it right. Is it correct that the performace information of all solvers will be automatically displayed by calling 'solve' function?

Yes provided it is switched on in your .OpenFoam-1.1/controlDict file which it is by default:
lduMatrix 1; |
