What you are saying is that it costs too much to fix the slowdown and my solutions are not good because of some reasons I have no idea of. This is your explanation for your unwillingness to fix it. Well, I have to accept that. However, having or not having time resourses on your side is abs

Renicing saned doesn't renice xsane automatically. Renicing one process influences only the future children. So your note is irrelevant. Look at setpriority(...) and/or sched_yield(). Good example for any of the saned copies: if(number_of_read_bytes==0) sched_yield(); __

Nobody requires the behaviour to be generalized to other scanner drivers and other scanner. To claim that something is a bug, it suffices to give one counterexample of "bad" behaviour, for one configuration. Here is one. (Well knowing that MS Windows allowed even a faster scanning, even many ye
