How Nydus’s RAFS v6 and EROFS over fscache Deliver Near‑Native Container Image Performance

The article explains how Nydus’s new RAFS v6 image format, built on the kernel‑native EROFS filesystem and integrated with fscache, overcomes the performance and scalability limitations of traditional OCIv1 and user‑space container image solutions by enabling kernel‑mode on‑demand loading, fine‑grained chunk deduplication, asynchronous prefetching, and superior I/O efficiency, with benchmark results demonstrating near‑native speeds.
