Document why we don't use ByteBuffer now
private final byte[] oneByte = new byte[1];
private final int[] state = new int[4];
+ // Note: the code used to use ByteBuffer but the manual method is 50% faster
+ // See: http://git-wip-us.apache.org/repos/asf/commons-compress/diff/2f56fb5c
private final byte[] buffer = new byte[BUF_SIZE];
private final int seed;
