Some times the number of IOPS needed to delete the snapshot is quite big and using the computer during this time is very very slow. For example, an xterm takes over one minute to start. Deleting the snapshot can take a good five minutes to finish. I was thinking of using gsched to alleviate the effect a bit. I am wondering if that would help? I just want the computer to be usable during the snapshot's removal.
