Fabio, I'm working on a similar solution, although I'm experimenting with SGI's KAIO patch to see what it can do. I've had to patch the kernel to implement POSIX style signal dispatch symantics (so that the thread which posted an I/O request doesn't have to be the one which catches the signal). Are you taking a similar approach, or is the lack of this behavior the reason you are using so many threads?
