Transfer speed question

So the transfer speed to my NAS at home from my seedbox has been just under 50 Mbps on a 50/25 internet connection. I’ve just upgraded my internet to 100/25 but the download speeds have only gone up slightly. Is this normal or is there a setting that I should be changing on the NAS end? (see box says Limit: 164 Mbps)

There are a lot of variables here, including CPU, memory, storage, and network factors. The bottleneck could be in any or all of those.

Whatever the problem is I don’t think as the above poster states syncthing would be it until at least all the other issues are tackled

I have two syncthing as containers running on the same computer syncing different RAID arrays and as a test I created an 8GB file and it transferred at +600MB/s

Granted that could be RAM talking but regardless the bit pushing was done by syncthing so clearly it’s no slouch

Is there somewhere that I can’t see, that has a default speed setting? Just seems weird that it’s downloading nowhere near what my internet speed will allow?

Two questions:

  1. Are you testing with a single large file or a large number of small files? There is significant overhead when transferring each file due to how Syncthing works (e.g. for security reasons), so it’s always going to be slower than just sending the same files in an unencrypted form over the network.

  2. Is the hardware somewhat decent or rather slow? Syncthing requires quite a beefy CPU and fast storage in order to work at its maximum capability.

Files are around 4gb

I have a synology 218j

Not an expert when it comes to NAS hardware, but it does look pretty weak… If possible, I’d suggest testing with high-end hardware and see if you keep getting the same transfer speed there too.
