I just did a hotcopy to the local drive and I'll be switching the repo
path and testing some big transfers this weekend to see if performance
improves.
The issue with leaving the repo on the local drive is that the NAS is
a RAID and already backups to an attached usb disk that runs nightly.
The repository itself is 10GB at this point and represents about 6
months of work so the redundancy/backup is pretty important. There is
probably some combination of internal mirrored drives and backup
software that could be put in place to fix this IF this that turns out
to be the issue but ideally I'd like to continue using the NAS for
this.
