You could also wrap your input and output stream's with java.util.zip.GZIPInputStream and GZIPOutputStream to compress/decompress the data either side. They allow you to specify buffer sizes, so you could experiment to find optimum buffer sizes. Check out the java.util.zip package in the javadocs. Rgds, Adrian.
