Hello - frequently I turn on my external USB 3.0 disk and back. While my machine is copying and backing up my desktop becomes very sluggish. Is there a way to change that ? I am using CentOS 7.5 x86 with a very nice processor extra cores available and plenty of memory. There is no reason the "other" cores cannot keep the desktop going. Thanks, Jerry _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx https://lists.centos.org/mailman/listinfo/centos
