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.
