Definition - What does Monolithic Kernel mean? A monolithic kernel is an operating system software framework that holds all privileges to access input/output (I/O) devices, memory, hardware interrupts and the CPU stack.
Performance of microkernel vs monolithic kernel. up vote 11 down vote favorite. A microkernel implements all drivers as user-space programs, and implements core features like IPC in the kernel itself. A monolithic kernel, however, implements the drivers as a part of the kernel (e.g. runs in kernel mode). I have read some claims that microkernels are slower than monolithic kernels, since they need to handle message passing between the drivers in user space. Is this true?
