My Cloud EX2 EXTREMELY Slow Read/Write

[elitewebninja]

Hi,

I have a WD My Cloud EX2, with 2, 3T WD Red Drives setup in a RAID 1 configuration. I’ve been noticing that it seems excessively slow for a long time so I thought I would do a test or two.

*** I am ssh’d into the device and I’m directly on a share performing an rsync of a 3GB file ***

Tried to copy this 3GB file and I’m literally getting under 4MB/s. Painfully slow and it tool almost 10 minutes to complete.

Both transactions below are being rsynced on the same drive, and in the same folder.

This is the super slow rsync transaction:

---

root@WDNAS Files # rsync -avh --progress rhcsa.tar.gz rhcsa2.tar.gz
sending incremental file list
dry_total_size:3054353550
rhcsa.tar.gz
3.05G 100% 3.96MB/s 0:12:15 (xfer#1, to-check=0/1)

sent 3.05G bytes received 31 bytes 4.15M bytes/sec
total size is 3.05G speedup is 1.00

---

And here is one from a normal copy:

root@ubuntu01:/home/user/# rsync -avh --progress rhcsa.tar.gz rhcsa2.tar.gz
sending incremental file list
rhcsa.tar.gz
3.05G 100% 114.91MB/s 0:00:25 (xfr#1, to-chk=0/1)

sent 3.06G bytes received 35 bytes 119.81M bytes/sec
total size is 3.05G speedup is 1.00

---

Anyone have any ideas why this is this slow. I can’t run plex or any other apps on it because it’s so slow.
The drives are rated quite high even though they are 5400 RPM.

Any assistance would be appreciated.

Thanks

Thanks but you didn’t read my post thoroughly it seems.

I’m not going over the network… ANY network… I’m in the same directory ssh’d into the NAS copying a file to a new name in that same directory.

Anyone else have any ideas?

Try each drive in JBOD, to see if it’s a drive problem. If not, It’s probably the computer.

rsysnc wont do much speed
