\b[False as a general performance claim.] A <microkernel> moves services into separate protection domains, which can require extra messages, scheduling and address-space transitions. A <monolithic kernel> can often call a service directly within its own privileged address space. The <microkernel> gains isolation and modularity, but these do not imply greater speed. Efficient implementations and particular workloads can change the comparison; the architecture alone gives no universal ordering.
