The Hurd is slow because:
1. "Premature optimization is the root of all evil"
2. It's implemented on top of GNU Mach, which isn't the speediest microkernel on the planet.

3. It's not monolithic program as some other kernels ;-) Instead, "The Hurd is a collection of servers (user processes) that run on the Mach microkernel"[1] and communication between these servers (Inter-Process Communication--IPC) is expensive in GNU Mach. We hope L4 to solve this problem at least partially :-)
