I think one of the problems might be the fact that every mutable byte string needs to be converted to an immutable bytes string before it can be sent across a place channel, right? I have no idea how costly that is, but that could be a huge part of the overhead. Unfortunately, it seems that the result of most byte string operations is a mutable byte string (with no way to tell the system to place it in the shared area), so it might be unavoidable. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
