About this document
Enhancing Memory Mapped I/O Efficiency by Peng Xiao is a document available to read on EtoBox.
This document proposes techniques to improve the performance of memory mapped file input/output (I/O) for in-memory file systems using next-generation non-volatile memory technologies. It finds that existing memory mapped file I/O incurs significant overhead from constructing page table entries and handling page faults. It presents three techniques - map-ahead, mapping cache, and extended madvise - to reduce these overheads by up to 70% and improve throughput and application performance. Experimental result
