It is widely used in the high-frequency trading application, which strives for very low latency, mostly in sub-microsecond level.

When I first mentioned about memory mapped file in Java, I have outlined some benefits of using those files, and ByteBuffer class is key to operate them. Most of the differences between direct and non-direct ByteBuffer derived from the fact that one is inside heap memory while other is outside heap.
