It's back to the slow speeds downloading, I thought there for a few seconds it was going to do right when it started at 120 MBps then dropped to 40 MBps, then to 2.9 MBps which is like dialup for me. Man this gets tiring.

1. Galaxy or browser download?

2. Is it megabytes per second, or megabits per second? I presume megabits, as 120 megabytes per second would be 960 megabits per second, ie. almost using the whole speed capacity of a 1Gbit/s connection.

2.9 Mbit/s would certainly be quite slow. How fast did it end up there, over a longer period of time or quite fast after starting the download?

Have you tried on some other PC, and/or using another internet connection? Just to weed out that it isn't some Windows security suite thing or the ISP doing stuff. (I would probably test it by tethering my phone's data connection to the PC, to see that the problem is not only on my cable modem connection.)

I'm new to GOG, so I'm curious to know what "normal" download speeds are supposed to be?

I pulled down the 33 installer files for Baldur's Gate 3 last night, and I was seeing ~4.5-5 MB/sec average per thread. I played around with multiple simultaneous threads both in-browser and via wget, and I found that any more than six would cause a drop in speed. So it seemed to cap out for me around 30 MB/sec.

My connection is gigabit fiber, and I've seen Epic downloads hit 50+ MB/sec, so I know the limitation isn't on my end.

What browser are you using to get multiple threads?
And is that wget2, as original wget doesn't support multiple threads?

Or did you mean downloading multiple files at the same time, and not multiple threads per file?

Depends of your region, I am in Europe and usually, at least last times I tried, I got around max my bandwidth when I download via the browser ~ 800Mbs I am also on a gigabit fiber.

(I cannot try right now because I have a much lower bandwidth caused by some technical limitations)

I wrote it correctly MBps, not Mbps I have a Gigabit connection, and I get 120 MBps (MegabytePerSecond) max on your Fastly servers, My speedtest is 1.2Gbps (GigaBitPerSecond) 1,200 Mbps. This is a browser download, and no I don't use WinBlows, I use Linux Mint, and it's a wired connection, and my wired network in my house is a 2.5GbE, My router is a WiFi 7 and all it's ports are 2.5GbE, my switch is a 2.5GbE switch, CAT 8 cables, the port on the back of the modem is a 2.5GbE port. No I don't need to test from one of my Other PCs I can download from anywhere else at full blast of 180MBps, if their server has the ability. Fastly servers suck. Right now I'm trying to download a game from GOG and the Fastly servers, and it will start at 120MBps, then in two minutes time it has drizzled down to 2.29MBps. Fastly sucks.
I'm able to saturate my entire bandwidth because I'm set up correctly.

Does wget work with GOG offline installer links?

Is that per download thread, or the total maximum speed you get even if you download e.g. several files at the same time?

tl;dr: Yes Fastly CDN appears to be slower than e.g. the Akamai CDN that Galaxy uses.

I wonder what that "120MBytes/s for a few minutes" is, I've never seen such behavior with browser downloads. I have a 75MBytes/s internet (600Mbit/s) and I get around 20-34 MBytes/sec with a browser from GOG, there is some variance depending on the time of the day I guess. That doesn't seem to depend on the number of download threads, or at least there doesn't seem to be any arbitrary limit per download thread even though downloading two or three files from GOG at the same time may make it more certain the download speed stays up.

Experimenting with some other GOG Fastly servers (with a hosts file) besides the closest one the GOG normally connects me to, many if not even most the Fastly servers seem to have a limit of around 5 MBytes/sec per download thread. So if I download only one file, I get max 5 MBytes/sec, with three I get 15 MBytes/sec total etc.

I'm fine with the download speeds I am getting, even if they don't utilize the whole of my 75MBytes/sec connection. If I can get at least around 20MBytes/sec from GOG currently, that is fine to me. Maybe in 5-10 years it will not be enough if the game sizes keep growing and are 10x of what they are currently, 4 terabytes for downloading Baldur's Gate 6 or Cyberpunk 3445. Game sizes just keep growing more and more, not sure why, is there no end to it at all? 16x HD textures, or audio voice with 1GHz sample ratio for crystal clear uncompressed audio, hundreds of hours of spoken recorded dialogue in 50 different languages?

I do seem to get better download speeds with Galaxy (which to my knowledge apparently use Akamai CDN). The last time I tested it (which was quite a long time ago, last autumn), I got up to 70 MBytes/sec when downloading an offline installer with Galaxy. Nice, I admit, but not nice enough to force myself to download with Galaxy. If I am going to download a bunch of updated game installers over the night, it doesn't matter to me if they download in 2 or 5 hours, I'm sleeping.

I'm not sure. I was never able to get it working ... but then I had the same issue with curl, until I was clued in.

The primary issue is that browser links are not the true links, and you need to follow where they refer to, and you also need a cookie file.

You can do that with curl, and because curl is only single thread, you need to couple it with something like aria2 or maybe even the new wget2, which I haven't tried yet, as it is 64 bit only. Those two feature multi-threads for downloading.

With Fastly, you need a downloader with multi-thread capability, otherwise it won't be any faster than using a regular browser.

Free Download Manager 5 is another good option ... haven't tried FDM6 yet.

That's one file one thread, the game is a 15.3GB sh file, Beyond a Steel Sky, this is the Linux install file. and I thought for sure it was going to act right, but nope, started out at 150MBps then within two minutes drizzled down to 3MBps. Sure be nice to be able to play the game I bought without having to wait 2 hours for it to download at this miserable speed.

I'm getting around 15-20 Mbytes/sec speed (fluctuating) for that same file at the moment. Not great but something I can bear with, especially as it is now Sunday evening so possibly not the speediest time.

Yeah different Fastly servers seem to give a bit different results... You can check the IP address of "your" Fastly server with:

nslookup gog-cdn-fastly.gog.com

You can check its approximate geographical location at https://www.ipaddress.com/ip-lookup if interested. I tested some other Fastly server by using the hosts file, e.g.

146.75.33.55 gog-cdn-fastly.gog.com

(that is a different server from what I normally use)

I have posted several threads with screenshots showing how it's Gog, and only Gog, with such slow speeds. In one screenshot I showed how I was downloading two files from two places simultaneously with the same browser, on the same computer, on the same wi-fi, etc. etc. with one getting around 40MB/s and Gog getting around 4MB/s.

It's apparent that Gog doesn't care. And trust me, when the average consumer makes their first purchase here and sees such a discrepancy in speeds, they won't make a second. Which is why it's baffling that Gog doesn't care. But actions speak louder than words, and actions prove Gog doesn't care about these atrocious download speeds.

For me, I can't EVER, and I mean NEVER get more than 5MB/s. It's almost like there's a throttle making it so. I get 30, 40, and 50 plus from every other website except this one. 5 is max.

And yet, by their actions, Gog doesn't care. (It doesn't matter if some blue pops in here and SAYS otherwise. Actions speak, not words.)

The Fastly server you use does seem to limit browser download speeds to 5 MBytes/sec per file (so you might get e.g. 15 MBytes/sec if you are downloading three files at the same time). I got similar results when testing your server earlier, using the hosts file method.

My local server acts differently, now I get around 15-20 MBytes/sec (the best I've seen is 34 MBytes/sec), and I get the same total speed regardless if I download one or two/three files at the same time, so in my case the download speed will not multiply with several parallel downloads.

Then again when someone from Australia tested what speed he gets on "my" server, his download speeds didn't seem to improve from his default server, so go figure...

EDIT: Well, I retested your server, and now it actually seems even worse than weeks ago, ie. I was getting max 4 MBytes/sec total from there, regardless how many files I downloaded at the same time. Yeah that is quite bad.

Fix your speeds GOG. Why should I or anybody else buy games from you when you have proven you don't care about the download speeds to get these games. Bad publicity is not going to look good if thousands of us give you bad reviews everywhere, your profit margin is going to sink so low you may consider bankruptcy as your only option, you used to be good, now with your uncaring attitude you'll end up in the waste bin next to other companies that made the same business ending bad decisions you're making right now. I think I'll have my other computer start downloading all of my games, when it has finished, I will never download a game from you again, and never spend another penny on you and your shabby service. Bad reviews have a domino effect. I'm curious of what changed to make you go from a good company to being the worst around. Do you have a newish person running the place now or something? Well if that's the case, they're running the company into the ground with their decisions. Be good or be gone.

Downloading from the website is slower and will probably not be fixed. I use Galaxy, which gives the download speed you're probably looking for. With the browser, I get around 4-5 MB. You could try using a download app like Internet Download Manager which has increased the speed of my downloading from the browser before.

The download speeds for Galaxy are fine. Sorry this sounds like first world problem. Lol. Try downloading games with 1mb or less download speed, then come back and cry to me. I used to do that while living in the countryside.
