S Hollander updated IO-726:
---------------------------
Description:
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.
