Well, the current version of Lark really doesn't really support anything *but* character streams... that and synchronization, if my measurements are correct, amount to >50% of the difference between XP and Lark. It is clear and (sigh) not surprising that method-dispatch-per-char is, well, less than optimal. Thus my plan had been to move to a three-arg-read read call. As a result of this, I'm a bit conflicted about James' suggestion that we lose the int read() methods. While they are a surefire way to run slow, I spent enough years in Unix that doing things via getc() feels natural and I appreciate its advantages; assuming of course that getc() is a macro with buffering, which of course a Java method dispatch, uh, isn't. Nice thing about stdio is it made it easy for the programmer to pretend to do character streams without having to really do serious per-char work. -T. xml-dev: A list for W3C XML Developers.
