> A very useful tool for improving performance with disk-based IO is the use of memory mapped files. I propose an {{InputStream}} that provides a bridge between memory mapped files and the {{InputStream}} ecosystem.
> In my limited performance tests, the use of the MemoryMappedInputStream provided a 25% increase in throughput.
