Fast CIFS - Slow Local Copy

[eastabrooka]

Hello everyone I need a little help here :).
I will try to be as detailed as I can and stick to the guidelines in the before you post page.
Current setup:
1X Windows 7 Desktop,
1X Netgear GBE Switch.
1X HP N40L

The N40L is running the latest Freenas release FreeNAS-11.0-U2 (e417d8aa5)
8gig ram
4x250 GB HDDs in Raid Stripe
1x 3TB Hdd.
( All HDDs are plugged into Sata -
The 3TB Disk benches 50 MB/s + when using CIFS.
And the Stripe array will max the Gigabit link. ) - Actually really happy with this. Love using Freenas.

I look on windows task manager and I saturate my 1GB link to 100% so I know the disks are capable of sustained throughput.

Here is the Gotcha I cant understand.
I want to copy from the Stripe to the 3TB Disk every night - So I log into the Freenas server over SSH.
And do a ' mv /mnt/StripeVolumeMedia/ /mnt/ThreeTB/Backups/' - And it just is really really slow.
I then set up rsync to do this ( Locally, with this command )

rsync -azP /mnt/StripeVolumeMedia/ /mnt/ThreeTB/Backups/
And its reporting 2,628,731,084 90% 3.61MB/s 0:01:15

3.61MB/s - Is just totally slow !

I want to ask the Gurus of Freenas why am I getting such slow local copy performance, but getting such amazing CIFS throughput. I have looked though the forums finding

And doing google searches using site:forums.freenas.org to your search request as warri suggests.

But I cant seem to find anything that fixes this problem.

Thanks for any help.

What SATA port did you use for the 3TB drive? If you used either the one in the ODD bay or the eSATA port, are you running one of the hacked BIOS's on your N40L?

Hi Gpsguy, Yes, I believe I am running the 30/09/2011 Bios Mod from TheBay which allows 6 ports of AHCI SATA 3gb/s.
The 3TB Drive is plugged into the ODD Sata port. And the stripe is on the Sata Backplane.
Thanks,

OK - just making sure you had done that.

There is a new Bios out - Dated 01/08/2014 http://www.nathanielperez.us/blog/hp-proliant-n40l-bios-modification-guide that I will have a go patching. But I am hesitant to believe it will fix, after all, I am getting good - to - great performance on the SMB share from this drive currently.

Its just the 3.61MB/s seems like there is a bigger problem for a local copy.
