USB Disk IO

CentOS 2 Comments

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

  • Are you performing the backup as your user during the same login session? Or is it a separate process/separate login that’s doing the backup?

    It’s possible that the I/O elevator is balancing your backup session with the I/O of the backup, making any disk activity by your login session an equal priority (i.e. competing for resources).

    You could always use ionice to make your backup process use idle resources.
