Small kernel size
Doesn’t have to recompile the whole kernel to fix a bug/add new feature
Small sized kernel = Increasing speed
Memory protected user-space
Independent component separated from others
Virtually any component can fail — and be automatically restarted — without affecting other components or kernel
Super fast processing speed (*NIX)
Support SMP (symmetric multi-processing)
Allows multiple applications to run in parallel while extracting the maximum performance from every processing core
Maximum Portability
Allows developer to compile and build an application on the same machine
