RN104 - Really Slow Copy Speeds
Hey guys, I'm copying a share from one volume to a new volume through SSH using MC (Midnight Commander) and I'm getting an avg of 6.33MB/s. Going to take 35mins or so to copy 14GB.
I know this...
- Firmware is 6.9.5
- Syncing? Well the new volume is a single empty disk. I suppose the NAS might be formatting it in the background?! Not sure.
- It always seemed slow to transfer stuff over the network but I was never copying a file from one volume to another to benchmark it.
- I have not checked Disk Health, I'm certainly hoping this brand new drive is A-OK.
- No anti-virus.
Hi WiredRacing
A new disk might be fine and dandy until the courier starts bouncing it around in the back of the truck :)
This could be a disk issue. Can you download the logs and find the log file: disk_info.log
Post the content of that log-file here (masking any serial numbers of your disk).
Thanks
True and doesn't seem to be...

Model: WDC WD100EFAX-68LHPN0All three disks look fine to me, and since this is JBOD there shouldn't be any issue with sync.
MC is running on the NAS?
Perhaps try a test using a backup job (configured in the web ui) to transfer the same share (to a different target on the new disk) and see if that shows better throughput. Might be good to reboot the NAS before you do this.
Yeah so last night I already added a backup job while the 310GB share (eta of about 7hrs) was chugging along. This morning neither had completed and the MC SSH'd (yes SSH'd into the nas, using MC on the NAS itself, no network copying in play here) copy of one of the shares was at half it's avg throughput (presumed the other half of the bandwidth was taken up by the backup process).
So backup process is doing a share right now and MC is actively copying files with a reported avg of 5.45MB/s (current large file it's on is 4.8mb/s).
So painful.
Whenever this finishes I'll run the performance test I see others run. I'll also try copying a file in the inverse direction to see if it might be related to the drive hardware/firmware.
