Readynas 104 - Slow transfer speeds

Dear all, I recently lost all my data to corruption of the array of my RN104. I've since then recreated an entirely new NAS based on NASware 4.0 TB drives in RAID5. I have also thoroughly sea...

root@miniNAS:/# dd if=/dev/zero of=/TEST10/benchmark.bin conv=fdatasync bs=10M count=200
200+0 records in
200+0 records out

Thanks for the tip Jak, basically I'm getting more than double the speed locally than through the network... weird innit? Would that point towards something?

~~Additionally, I saw that there is a finetuning app called SMB Plus.. but no apps are showing in my NAS Admin web. Any clue why they'd be missing?~~

Nevermind, I figured it out by connecting in ssh & doing : apt-get update

Upon rescanning the repositories, the apps reappeared.

However, SMB Plus now gives me a choice between SMB 3.0 (win8) and SMB 2.1 (Win7). Since I'm using Win7, should I switch back to 2.1?

depends, you running a server 2012 or 2012R2 or higher dns server on lan?

if no server then setting for win7 best bet, if have dns server on lan then you may see oddities locking to win7 version.

I have 314 and 104 here, both run about the same speeds transferring iso files over gb lan.

No I don't run any server, it's quite a basic home setup with 3 windows PCs in Win7 and one linux box.

I'll try the setting then.

I am really surprised that your RN104 runs at same speed... Could it be the drives used? or maybe the smb conf?

Any chance you could copy paste your smb.conf here, for me to compare?

Your speeds look fairly typical for the RN104 to me, so I think you are limited by the processor.

The RN314 is faster (especially on writes).

from my OLD (Ubutun 12.04 LTS) box, with the NAS share mounted in cifs, I get 46MB/s, which is at least 6MB/s more than from my windows PC.

I have been tweaking smbconf according to : https://www.arm-blog.com/samba-finetuning-for-better-transfer-speeds/
and I did gain a few MB/s as well.

I wanna take your word for it that the CPU is the ultimate cap on this, but if someone has managed to build a RN104 with SATA drives going above that, I'm most interested !

I was mistaken about speeds, when I had last done a direct copy/paste it was to a non raid drive on the 104.
presently with all 4 discs in raid 5 I run (using a 7.5gb iso test file) approx 50Mbs on the 104 and 98-112Mbs on the 314
sorry about that

edit:corrected figure
also this is from win 10, server 2008r2, server 2012r2, Mint 18.1 sources.. all systems (sources) are close enough to call it no difference

*MB/s (or MBps), not Mbs
50Mb/s would be very slow ~= 6MB/s
