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 searched for improvements in transfer speeds : my ISP box provides 1Gbit so I've connected both my PC through a 10m CAT5E RJ45 cable and the NAS through a 3m CAT6 RJ45 cable to the box.
Now upon searching in the forum, I discovered a previous thread where it was advised to use NASTester for testing perf, as well as iperf3.
Clearly the iperf3 seems to give a correct 1Gbit speed, while the NASTester shows asymetric read & write speeds .. While I'm above a 100Mbits, it's not really the 90-100MB/s I'd like to see.
I think your numbers are not too bad. The RN104 is weak because of its cpu and ram. I have an RN104 and an RN204. While the 104 is doing 45 to 50 the 204 is doing 85 to 90 MB/sec (write speed) under exactly the same conditions infrastructurewise.
If you like you could go through a collection of hints how to improve statbility and performance of RN104 following this link:

I've just tried to do bonding on both adresses & to set it to adaptive load balancing. Changes nothing in terms of speed... I'm afraid the slow CPU is indeed the culprit... I am wondering if I should scrap it and try a RAID10 maybe? Would that give me much performance that the NAS can actually handle?
I havent started filling it, so there is still time.

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?
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 !
