Slow upload from PC to NAS

Post by SuperSo84 » Wed Jan 15, 2020 11:33 am

Hey everyone, new here. But I'm running into an issue of severe slow speeds while uploading to my QNAP 251+.
Running 2x 10tb Ironwolf NAS drives in RAID 0 (Yes I know)
Using a USB 3.0 5Gbps Network Adapter which runs to a MikroTik 10g switch using CAT 7 cable 10' long
On my PC running a 10gbe ethernet connection to the switch using CAT 7 cable 10' long
All equipment is less than 2 months old.

When downloading a 7GB file from NAS via mapped drive on Win 10 I get around 390mb/s
Uploading the same file back to NAS, I get 50mb/s

Not sure if I'm in the wrong, but I'm pretty sure I was receiving at least 110mb/s on my gigabit connection, how is this slower?! Any assistance would be appreciated.

try a direct connect (pc to adapter card..no switch)

I have a cheaper trendnet 5GbE adapter..that is hovering just over 300MB/S to my 951X .. not great..but certainly better than 1GbE

Yeah, I have no problem with download from NAS which is great, it's the upload that's frustrating.

I don't know if this is related but I've struggled with file transfer speed for some time. As an example, over wifi on the same network, I can download a file to my mac using AFP in apple explorer at about 40MB/s (I've just timed it). If I use File Station, QFile or QfileHD, I get about 1MB/s. Same file, same server, same network.

Any ideas what's going wrong?

Have you ever found a solution for this issue? I've exactly the same issue with a TS-453s Pro, qna-uc5g1t, 3x EVO 860, MikroTik 4-port 10G switch, CAT7 cable and a ASUS 10G PCIe card.

I'm also getting around 400mb/s in download speed and 40-50mb/s max in upload speed.

So I have the same issue, slow upload speed to another network drive. I noticed that this problem started after the update HybridMount, anyone know how to downgrade the app?

Has anyone found a solution?

I have a TS-453A with the QNAP QNA-UC5G1T USB to 5Gbe ethernet adapter. My workstation has an Intel X520 10Gbe NIC and both the NAS and my workstation are connected using a CRS305-1G-4S+IN SFP+ 10Gbe switch to connect the two. All of the upstream networking gear is Unifi so I am completely unfamiliar with Mikrotik configuration.

When testing with iperf3, the maximum I get between my workstation and the TS-453A is between 500 and 600 Mbits/s. If I do an iperf3 with a laptop connected to an upstream 1Gbe switch, I can achieve the full 980+ Mbit/s from my workstation.
