Ok. And yes I mostly agree, although I can imagine circumstances where a pretty simple rate limiter might help significantly - albeit be something that has to be tweaked very specifically for the situation/hardware rather than being auto-tuned. If I have the time I may look into posix_fadvise() to begin with (but I'm not promising anything). Thanks for the input! -- / Peter Schuller
