It occurs to me that the code is effectively buffering the output from a
BufferedReader (or BufferedInputStream).
One would expect these classes to be reasonably fast, however the JVM has to
do locking and other checks in order to support multi-threading. It has to do
this for each read() call.
Rather than implement the buffering directly in the compare methods, it
might be better to implement a generic, non-threadsafe buffered reader/stream
that can be used in situations such as these. [No need to wrap the original
input in a buffered version first]. It would be a non-threadsafe version of
BufferedReader/InputStream.
The original code should then work without any change other than to add the
filter.
