side question...would using a file transfer software like filezilla solve the issue?

Yeah, I think I've figured out that it is a buffer issue (I've eliminated any hardware being the issue by directly connecting the server and PC. Got all of the same speeds, even with different cables/ports). Turned off a bunch of limits in the NIC properties (flow control, interrupt moderation, etc.) and maxed out receive buffers to 4096 and transmit buffers to 16384 and jumbo packet to 9014 bytes and that increased the speed from 220-250ish MB/s to around 400-425MB/s from PC to Server but I am still getting full 1.1GB/s when going Server to PC. Also, when I ran the short iperf test it still showed the same bottleneck. I had a thought that maybe increasing the buffer on the server might increase the speed but I saw your post here and based on what I think is being said, it doesn't look like that is an option/would help. Would you agree?

I gotcha...I'll start working on swapping around stuff. By chance, does the extended iperf report I posted earlier show any red flags to you?

Here you go https://pastebin.com/cfT71GRx. Thanks for the suggestion. I'm still new to networking so I'm not 100% sure what I'm looking for, but it looks normal?

If it was network, wouldn't the issue persist when downloading from the server?

Hi all, cross posting from my reddit post. Got some helpful tips on how to diagnose but still not sure what is going on or how to fix it. When building my server I bought a pair of HPE 10Gb 561T NIC's for both the server and my main PC. I just got a 10G network switch (Netgear GS110EMX), and when testing everything I'm getting a weird speed issue. When moving a few single large files from my PC to the server, it starts out at 800-900MB/s and drops to around 220MB/s almost instantly (writing to a Samsung 990 Pro 2TB cache) but when moving from server to PC I get the full 1.1GB/s. I am not running any kind of VM/reverse proxy or using any web based FTP. It's simply a networked connection from the pc to the server via the 10g switch and the router (both PC and server are direct connected to the 10g ports). Specs for server are: Cache Drive Samsung 990 Pro 2TB Main PC Drives are: C drive Seagate Firecuda 530 2TB (the file I was moving was from this drive) D drive (Dynamic drive for 4TB minus headroom) SK Hynix P41 & Samsung 980 Pro I ran iperf and got these results which mimic what I saw when transferring the files. I just can't wrap my head around what could be going on since the issue is only one way. Any thoughts?

So this ended up being the problem. I did not plug an ethernet cable in. Soon as I did that, it started working no problem. Appreciate the help!

I'll give it a shot. Thanks!

No it never worked. I was trying to launch for the first time. I have not. It was my understanding that virtualization had to be turned on but I can give it a shot. So I just realized I don't have it hooked up to my router yet. Because of my office setup the router is on the far wall and my monitors/desk are on the opposite. So it def. hasn't given it an IP address which may have been the problem? Will throw it on a cable and report back.

Hi all cross posting after a reddit reply suggested I'd get faster response on here. I am trying to move to unraid from my little 2-bay synology but am running into a problem. Once I get to the Lime Tech. screen with OS, OS/GUI, etc. I select either OS or OS/GUI and the OS starts to load but then something happens and I get a no display output and my monitor just continuously flashes with the no output message. Hardware:intel 12400 asrock z690 RS ddr4 TeamGroup T-FORCE VULCAN Z 32GB (2 x 16GB) DDR4-3200 PC4-25600 CL16 HP 561T (for some reason this is showing up as a bootable drive in the bios. no idea why but I've just been ignoring it for now). Edit: there are two HDD's installed at the moment and a 500gb nvme. Windows is installed on the nvme. Intel virtualization and vt-d are turned on and I have the HDMI cord plugged directly into the mobo. If any other info is needed just let me know. Thanks for any and all help!
