RandomAccessFile's unbufferedness

[Anthony Green <green@xxxxxxxxxx>]

I was writing a little code that uses RandomAccessFile and was 
astonished at how slow it was.  A little googling tells me why.. it's 
using unbuffered I/O.

I modified my code to use a buffered RandomAccessFile class from 
http://uio.imagero.com/ and it's almost 10x faster now.

This made me wonder where we're using RandomAccessFile within GNU 
Classpath.  It looks like it shows up in a few places that could use 
some buffering (image i/o, and maybe even zipfile).  I don't recommend 
using the uio library for this, but writing a little buffered 
RandomAccessFile for internal use seems like it should be easy (google 
will point you at many simple versions).

I don't plan on doing this myself, but just thought I'd mention it here 
in case somebody wants to look into this.
