Problem with transfer to my NAS server

Hello everyone, I need some help with my NAS server. I have an HP PowerEdge T110 II computer with 4 HDDs (2x WD Blue, 2x Seagate for Servers) plus one SSD for the system. When I set everything up on OpenMediaVault, it looked fine, but when I tried copying files from my MacOS 26 computer to the server, the transfer started at about 60 MB/s and then dropped down to almost 0 — and this repeated roughly every minute. I searched for a reason but couldn’t find anything.

At that time, I had 2 GB of RAM, so I decided to take a chance and bought two identical RAM sticks online. Today I installed them, so now I have 4 GB instead of 2, which should be enough, but the issue is still the same. I reinstalled OMV several times, but that didn’t help either.

What can I do now? The server is connected to a Funbox 3 via an Ethernet CAT5e (or faster) cable, and I don’t see anything that could be causing the problem. Could it be macOS? It’s similar on Windows, so probably not. I should mention that when I use the Blackmagic RAW speed test, it consistently shows around 55 MB/s, so it’s not that bad.

Please, any advice would be appreciated! If I can’t fix this, I’ll just install a different system. Thanks in advance

Are your file transfers many small files or one large file? What service are you using to do file transfers?

I usually send Mac file apps for test (for example gimp app files). I use standard service for macOS: SMB

Unfortunately, I can't help you except to say that I gather from forum posts that SMB and Mac have a difficult relationship.

Okay, thanks. I tested this also on windows laptop and I had the same problem:(

After many responses from users, it seemed appropriate to close this thread. Some time after writing this post, I bought another RAM stick, so I finally have 8 GB of RAM. I returned to OMV and I have to say that now I’m very satisfied. The transfer speeds are satisfactory and the performance of applications running in Docker is great. I connected my Mac computer via an Ethernet cable and now I have a stable connection to my folders on the NAS. Thank you to everyone who wanted to help, and I hope that when I gain more experience in this area, I’ll be able to help others as well 🙂
