I noticed that I sometimes have through several hours 20% cpu usage by the cleaner. During the 20% usage, I have 50% iowait, leading to an overall slower system. Is this behaviour normal or is there something I can do on my part. If this is normal, I think it should be possible that I mount without cleaner and start the cleaner only if I am short on space. Is there any argument against doing this ? Concerning stablility, I didn't have a single crash until now. Thanks in advance Bye, David
