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. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
