Here's my suggestions, which are made mostly in ignorance, since I
tried to do anything like this with Cocoa.
Surely, no matter how optimized the basic string operations are, it's
going to solve the problem: Get it efficient enough for a 1M file, and
2M files... and so on. There has to be an algorithmic solution.
It looks as though the setNeedsDisplayInRect:avoidAdditionalLayout:
of NSTextView is highly relevant, isn't it?
Also, it's probably NSLayoutManager that's making the unnecessary
so, if some subclassing needs to be done, that's probably what needs to
Hope this helps a bit.
