For decades, microkernels offered superior security and modularity but suffered from a massive inter-process communication (IPC) performance tax. But what happens when the hardware finally catches up?
Thanks to modern silicon features like hardware capabilities (such as CHERI), Single Address Space OS (SASOS) designs, and zero-copy message passing, the historical performance advantage is officially flipping. In this video, we explore how next-generation microkernels are turning hardware-enforced isolation from a bottleneck into a major performance feature, allowing them to finally outpace traditional monolithic kernels like Linux at scale
