This is pretty useless on my system because the loss of responsiveness is mostly caused by the disk accesses and not by cpu usage. I have added a usleep() into the copy loop which is executed every 3th loop. This reduces the cutting bandwidth to about 5 MB/s on my system. Something that limits the disk bandwidth used by cutting combined with a cutting queue would be ideal. Emil
