Canonical title: RFUSE: Modernizing Userspace Filesystem Framework through Scalable Kernel-Userspace Communication | |||
Question: Can FUSE retain userspace isolation while scaling data and metadata operations on many cores? | |||
Context: Traditional FUSE communication adds context switches, copies, and centralized contention between the kernel and userspace daemon. | |||
Method: RFUSE replaces the communication path with per-core kernel-userspace ring buffers while preserving existing FUSE filesystem implementations. | |||
Evaluation: workloads=data and metadata filesystem workloads; baselines=traditional FUSE and in-kernel filesystems; metrics=throughput and scalability; results=comparable throughput to in-kernel filesystems; no exact value in official abstract | |||
Interpretation: The main bottleneck is often the shared IPC path, not the filesystem logic itself. | |||
Reusable lesson: Shard cross-boundary queues by core and preserve compatibility above the transport layer. | |||
Applicability: Userspace filesystems whose daemon logic can remain unchanged. | |||
Limits: Exact workloads, hardware, and quantitative comparisons were not extracted from full text.</nowiki> | |||
