In fact, the file access is supposed to be WAY faster now than in the RAID case.
As noted in ELOG 9511, it was SCSI-2(or 3?) that had ~6MB/s thruput. Previously the backup took ~2hours.
This was improved to 30min by SATA HDD on llinux1.
I am looking at /opt/rtcds/caltech/c1/scripts/backup/rsync.backup.cumlog
In fact, this "30-min backup" was true until the end of March. After that the backup is taking 1h~1.5h.
This could be related to the recent NFS issue?
