1. BufferedInputStream is working fine. I've looked at the source, and it correctly tried to read data only when its internal buffer is exhausted. Most read calls reference only the internal buffer. When the data does get read from the underlying stream, it tries to read it in large chunks. (Of course, if the underlying stream returns very little data, it is a different problem.)
2. It is hard to believe that reading a byte at a time is a bottleneck, but I've just quickly written a LineReaderInputStream, which is derived from BufferedInputStream, so all the searching for CRLF/LF happens very quickly internally. The source is attached. Just call readLine() method, and you'll get Strings out of the stream. You can interleave all regular stream operations and readLine() calls. However, if you wish to use readLine() *after* using the stream's read() methods, make sure that you do not inadvertently pass this stream to anything that is buffering the stream's data (or your strings may get consumed via buffering). - Igor >>> I looked at the source for BufferedInputStream and it looks like >>> it tries to fill the empty space in the buffer each time you read from >> it (for a socket connection it will read more than one packet of data) >>> instead of just doing a single read from the underlying stream. >>> >> >> Ok, then the byte-by-byte reading in CIS when parsing the chunk header >> might well be the problem.
