Slow transfer speeds Steam Local Network Game Transfers

[Saeris]

What would be a good way of debugging slow speeds with the new transfer feature?
I'm capped at around 30 MB/s - if I cancel the transfer and proceed with a regular download, I get my usual 60-80 MB/s.

(This was tested on the Deck transferring from a Windows machine connected to 2.5GbE network.

in my case i just started using sshfs to copy files around and that is vastly faster even by wifi.

getting this same issue, im directly connected from my laptop to my desktop using two 63 ethernet cables and one 2.5gb switch

Still doesn't work properly, I downloaded 2 TB of big games to my old PC that wouldn't run most of them just to make use of free space and be able to get them quicker than my ISP would allow, still have to download via internet since its twice as fast

I'm getting this issue as well. There should be about 250Mbps between host and a download client (it's a ethernet over powerline connection connected at a switch). I get 80 at max.

I tranfer games via WLAN. Turns out let the router reset the WLAN-Channels during transfer the transfer speed increased enormously. Sorry just can tell the german terms for a FRITZ!Box. "WLAN > Funkkanal > Kanalbelegung aktualisieren." WLAN will be briefly interupted, so please make sure nothing important is running in parallel. This increases the transfer speed from 13 MB/s to 101 MB/s.

While not anywhere near as bad as what some people are reporting here. I am getting 575Mbps when I should be getting closer to ~940Mbps. I will typically get 800-900Mbps from Steam servers.

Slowest link is 1Gb Ethernet
Both PCs of the connection have NVMe SSDs
Both PCs have high end CPUs 5800X and 5950X so encrypt / decrypt should not be a bottleneck
Router is not reporting any traffic on my network that would congest it.

It is probably whatever protocol Steam is using for the transfer. Probably not all that performant.

Hmmmm, one thing I'd check too is to see what the wifi on the deck looks like. It's hard to tell sometimes depending on how the router is setup as well, but 2.4 ghz wifi vs. 5ghz can be a real game changer depending on the situation.

2.4Ghz is what it's been on for ages, but 5ghz is more recent and has more 'channels' on it to broadcast on. Problem with 2.4, is it only has a handful of channels, a few more in some countries than others but there's like 10-15 give or take, and if there's too many devices nearby clogging all the channels up it causes some gnarly interference slowing everything down.

I was amazed a few years ago when I got my first 5Ghz router and suddenly my tablet's awful wifi connectivity was gone in a flash, because, well, less devices are supporting 5Ghz, more now than then, but 5Ghz has WAAAAAY more channels available than 2.4 as well, so there's less networks trying to overlap.

Personally I'm near a school, and I don't know how many routers are truly in there as they're mostly on the same SSID, but the amount of routers competing with bandwidth on the 2.4Ghz channels is nutty compared to the 5Ghz, so if the deck's wifi happens to be connecting on 2.4, might see if 5 is better.

(Coincidentally, also a good thing to try if your Steam Link performance is completely useless on wifi normally)

I was using 2.5ghz on my laptop, that's why it was slow, thanks!

Over wired (wireless is even worse) network it is much faster for me to restore the games via USB 3.0 from a powered USB external drive than to bother with this horrifically awful steam network transfer.

it is absolutely horrific in quality compared to something like nitroshare; also I have noticed that this crappy steam version of network transfers fails A LOT often within a few minutes and will revert to downloading; you have to pause the download and then restart it to get it to go back to transferring over the network. Not sure what kind of reject IT guys steam has assigned to this, but damn this is just awful.

I'm adding myself to this thread since I've just tested this on my local machine and it's basically 1/5 bandwidth of my actual line speed (20 MB/s versus 100 MB/s directly from steam). From the peer status it's clear it's only using one single thread to stream the data. Why? Just keep adding threads until you saturate the ethernet/cap CPU speed or just not bother at all, And if it's using the same encryption protocol that come out from the WAN, again, why even do that if it's just over the local network?

Adding additional controls to the settings might make this useful (assuming it's fast enough), otherwise I can't really see the usecase IMO.

steam game file transfer seems to have a hard cap at 100Mbit.

I have 10Gbe Ethernet and switch and have tested to 9.8Gbits transfer so why has steam put a hard cap at such legacy speeds??

Steam downloads have been capped to help with bandwidth.

Steam Game File Transfer can help only if it is faster than the download.
I download at 450-500Mbits which is capped by steam.
Local Transfer is at 100Mbit which is useless if the download is faster.

What I have tried so far.
I have a Windows VM running on my 2x 10Gbe Sever into a 10Gbe Managed switch.
What I was hoping to do is install the appropriate games to stay up to date on the Windows VM then when I or any of my team mates came round we'll just need to download locally at up to 10Gbe speeds saving time and steams bandwidth.

Would be a good idea for steam to fix this as it will benefit them more if members can transfer game files locally, and save steams bandwidth.

Right now I have friends and team mates come over and I have to tell them to disable file transfer as it will take 5x times longer because of the hard cap.

Temporary fix found...

Set limit download to (1mb) 1024Kb x 1024 = (1Gbit) 1,048,576 multiply by Gbits in my case 10. but only getting up to 1.1Gb on transfer, better than 30Mbit or 100Mbit if you do not set it.

[Shadow Chaser]

I suspect the limitation is how many cores I assign to the Windows VM, this is probaly due to steam repacking and compressing the files before transfer. So I am capping out at 1.2Gbit. Will update when I test with more cores.

Else it's a hard cap from steam.

[Shadow Chaser]

Transfer limit not due to CPU cores.
Looks like there is a hard limit up to 1.2 Gbits. Hope steam can fix this.
