In a multiserver system, communication between different components
must use some IPC mechanism, which implies quite a lot overhead and
several context switches, compared to a monolithic kernel where it's
just an ordinary function call within the kernel. To get a multiserver
system as fast as a well-crafted monolithic kernel (like bsd or linux)
seems quite hard.

Having fast ipc primitives is one important issue, and that's where L4
enters the picture.
