제목	RFUSE: Modernizing Userspace Filesystem Framework through Scalable Kernel-Userspace Communication
궁금했던 점	Can FUSE retain userspace isolation while scaling data and metadata operations on many cores?
해본 것	RFUSE replaces the communication path with per-core kernel-userspace ring buffers while preserving existing FUSE filesystem implementations.
당시 조건	Venue: FAST. Year: 2024. Traditional FUSE communication adds context switches, copies, and centralized contention between the kernel and userspace daemon. Verification: official USENIX paper page and abstract; confidence=high.
실제 결과	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
왜 그랬는지	The main bottleneck is often the shared IPC path, not the filesystem logic itself.
다음에 기억할 것	Shard cross-boundary queues by core and preserve compatibility above the transport layer.
언제 맞는지	Userspace filesystems whose daemon logic can remain unchanged. Limits: Exact workloads, hardware, and quantitative comparisons were not extracted from full text.

+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.
