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
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).
