Extremely low transfer speed

[doutatsu]

Hello everyone!

I've just built my first NAS machine and have been struggling with a couple of things, but the main thing so far has been slow transfer speed. I've looked at various forum threads here, but still couldn't solve it.

I am using a CAT5e cable, so that should not be the problem. I am using WD Red disks which should have fast enough read/write speeds I'd imagine. Here is my build.

I've run a perf test and here are the results. As you can see it doesn't even hit 100 Mbps...

What's the NIC?

If I am correct this has "Dual Intel® Gigabit LAN". Per:
https://www.asrock.com/mb/Intel/Z370M-ITXac/#Specification

Just also figure I would mention it shows:

- Supports DDR4 4000+(OC)* / 3866(OC) / 3800(OC) / 3733(OC) / 3600(OC) / 3200(OC) / 2933(OC) / 2800(OC) / 2666 / 2400 / 2133 non-ECC, un-buffered memory
- Supports ECC UDIMM memory modules (operate in non-ECC mode)

Never trust a cable. Most of the time, networking problems are caused by bad cables. Most of them worked fine right up until they didn't.

Yeah, it does, but I didn't try it yet as I should get at least one of them working properly, right?

What is your point around ECC memory? I don't use any

Yup, that's what I read in other posts, so I tried different cables, I used them with and without the switch. No change whatsoever

What's the NIC?

You mean on the motherboard?

- Gigabit LAN 10/100/1000 Mb/s
- 1 x Giga PHY Intel® I219V, 1 x GigaLAN Intel® I211AT
- Supports Wake-On-LAN
- Supports Lightning/ESD Protection
- Supports Dual LAN with Teaming*
- Supports Energy Efficient Ethernet 802.3az
- Supports PXE

It is recommended to use ECC. Please refer to the "Recommended Reading" links in my sig; namely the one pertaining to "Hardware recommendations (read this first)". Just basically providing some guidance. ;)

Ah, of course. I've read plenty on that and while it is recommended, from my research it didn't seem like it was worth the increased price for a simple media server, where redundancy is appreciated but is not of highest priority to me.

a simple media server

Curious: why FreeNAS then? Is it because FreeBSD is told to be/known to be secure in terms of attacks?

EDIT:
On the other hand: isn't FreeBSD told to support less hardware than other operating systems? <- off topic

Why FreeBSD? I've only heard a bit about it, but FreeNAS is famous to be a number 1 choice for NAS and media servers. Having ZFS was a big boon and just generally I've been recommended it a lot, so didn't even consider other options.

Still hoping to get some help on this, I have no idea what else I can do. I saw a similar thread with similar problems and with my perf results, it seems like it is a networking problem? Would really appreciate some ideas on what I can try to diagnose further or things I could fix?

Directly connect server to the client with no switch in the way. Verify results in each direction.

Ok, so I did something else, as I couldn't figure out how to connect directly from PC to NAS. But based on other places, some recommended to just connect the NAS directly into the router... And voila, my speeds 1092 MBytes Transfer, 916 Mbits/sec Bandwidth
