Help troubleshooting rndp6000

Sorry. yes I'm only on 2.4 ghz due to old devices but that's ok lan is ok.

What is the best I could get for write speed for lan? It seems 115 MB/s is best I can get. I could upgrade ram and cpu maybe.

I found flow control enabled for wifi but not in lan device manager settings.

I have 20 tb to backup. anything I can do to speed up within reason is an option.

Gigabit ethernet (1000 Mbits/second) translates to 125 MB per second (for 1000*1000 bytes) and 119 MiB per second (for 1024*1024 bytes).

There is overhead (ethernet framing, IP headers, SMB protocol overhead) so you'll never see those values.  So you are at the limit of gigabit ethernet for large file transfers.  RAM/CPU upgrades won't increase your speeds.  The main reason to consider those upgrades is to speed up apps (including Antivirus and File Search in OS-6) on the NAS.  The upgrades won't speed up the file server speeds.

If you had current wifi you could certainly gets 25-30 MB/sec speeds over wifi. (translating to wifi speeds in the 200-300 mbits range).

Why not use both lan ports to double transfer speed?

Your PC only has one LAN port, so you are still limited to 1 gigabit for transfers to/from the PC.

If you have a lot of simultaneous users you can use Link Aggregation (using both LAN ports) to increase throughput.  But it won't improve the speed of a single client. 

About how many wired devices do you think will be accessing your NAS at the same time?

Only me. Could I add an extra lan to usb and have two lan ports for double the transfer rate?

I don't think Windows has much (if any) support for link aggregation.

What you could do is get a small multigig smart switch, and then put a 10 gig card in the PC.  If it's a laptop or an all-in-one, you could maybe use a 10 gig USB-C/Thunderbolt adapter - though I have no personal experience with those.  Cost would be in the $300-$400 range for the switch and PC NIC.  You do need a cat-6  cable for the switch->PC leg at least.

On the NAS end, you'd set up the switch to use a static LAG and the NAS to use round-robin.  

Not sure I'd do this with a Pro-6 though.  It's more advantageous if you have a NAS with 10 gig built in (RN52x or better).  

Thanks. So is multichannel SMB not an option?

The NAS has no controls to enable it, and I believe it's disabled by default. 

Also to get it to work you need to manually adjust the route tables on at least the NAS.  https://www.reddit.com/r/homelab/comments/5p6gy6/my_experience_with_samba_and_smb_multi_channel/

Thanks.

I can get a LAG compliant device. But do I need a thunderbolt device for 10G?

I already have one usb3 ethernet 1 gig port and another on the laptop motherboard 1 gig.

I could run one cat6 to each and do round robin bind for eth0 and 1?

When I googled, I only saw thunderbolt external adapters.

AFAIK Microsoft doesn't include support for link aggregation in "consumer" versions of windows - it's only in Windows Server.  There might be some third party solutions out there I guess.

Ok. Got it.

When you said you only saw thunderbolt adapters -- you mean for 10G, right? why not use two usb2 1G adapters since total is 2G not 10G or does this require a single adapter with 2G or greater?

So if I'm using Windows 10 -- even though it doesn't support LAG -- I can still use a Thunderbolt 3 10G and LAG managed switch and i can support both lan ports via static or dynamic link aggregation? Why is round robin used in bonding not 802.3ad in the ethernet bonding settings?

Is the limitation software (windows 10 OS) or hardware?

Here's a switch that might work?

Because Windows doesn't support link aggregation.

LACP is it's own mode.  The only thing you can configure on the NAS is the hash mode (which doesn't affect performance much).  LACP was designed for "trunking" multiple client connections between switches (or between a switch and a server). With 2 gigabit NICs it can deliver two gigabit data flows to different clients, but it won't deliver a 2 gigabit data flow to a single client.  A static LAG in the switch and round-robin in the NAS will deliver a 2 gigabit data flow.

The GS105E doesn't support link aggregation.  The GS108T does.  Though if you want 10 gigabit from the PC you'll need a multigig switch like the Nighthawk SX10.

The Thunderbolt adapter is one that I saw too.  I've never used one of those, so I don't have any personal experience with them.
