Not really.
Usually, the microkernel approach requires more memory footprint
and more CPU power than the monolithic kernel approach, if it achieves
same functionality. Because microkernels require explicit IPC, and
such IPC takes more instructions and CPU cycles than usual function
call.

Well, one can always use config(8) for that purpose.
