Java does not expose many of the I/O capabilities that are synonymous with high performance.
Examples include memory mapped files and asynchronous I/O. Heck, it doesn't even expose
non-blocking I/O.

Even ignoring these ommisions, there are other issues with the core libraries that cause
lower performance. Allan Heydon and Marc Najork of the Mercator project (see url below) have
a posted a paper titled "Performance Limitations of the Java Core Libraries" that discuss
both string and I/O related problems (among others).
