Zlib::GzipReader should wrap the GZIPInputStream in a BufferedInputStream for performance

java.util.zip.GZIPInputStream is not internally buffered, so every call to read results in a JNI call to decompress a small amount of data.

By simply wrapping the GZIPInputStream in a BufferedInputStream, the inflater overhead is reduced significantly.
