In modern operating systems, memory-mapped I/O (mmio) is an important access method that maps a file or file-like resource to a region of memory.
The investigation finds that the overhead of the Linux virtual memory subsystem, negligible on the HDD, prevents applications from using the full ...

Oct 19, 2014 · After emptying the Windows file cache between my sample runs, I see that my super-fast memory mapped i/o is 30X slower than what it was before!
With memory-mapped I/O (i.e. mmap), a user can map a file in the process virtual address space and access its data us- ing processor load/store instructions. In ...
