Downloads, not fully downloading

funchai Have you tried FDM for Mac Chrome/Mozilla?

You could also try increasing your pagefile. Or add an additional one on another drive. (I don't know how this works on Mac though).
Don't save to SD or exFAT

For PC, is memory remapping over 4G enabled in bios while using a x64 OS?

SLR either is intentionally trying to limit it to a single download per IP, or has seriously broken bandwidth management code. There is nothing wrong with the users set up and page file has nothing to do with this at all.

This is a problem with SLRs content download system. I see it any time that I try to download more than one file at a time on one IP. There are also reddit threads and other posts with users confirming this.

Re download managers:

I dont have time to dig into the code, but it appears this is intentional from SLR. Its not a bug in the DL managers. Ive tried many and the last one was Chromo Download Manager.

If you set concurrent > 1, it works but then SLRs "broken" code to limit to 1 kicks in and in most cases ends up borking all concurrent downloads. I wish they would just limit it to 1 and not even try to start the secondary ones.

When concurrent = 1, the problem seems to be is that SLR is intentionally generating short lived temporary download links. So if the DL manager starts them right away, not problem. But if it waits, like when concurrent = 1 and and existing download is in progress, then when it gets to the queued ones the links have expired. Thats why it returns and HTML page instead of an MP4, and is probably why sometimes even on the site clicking links on pages that have been open for a while generate invalid mime type errors as it returns html instead of mp4, but the mime type was already in the header.

Im not trying to scrape the site or anything. Its just that I have 2 internet connections, both not very good and I live in a remote place. So streaming always causes lower quality and often is like watching youtube in the early 2000s. Lots of pauses for buffering etc... thus I download... and this is quite frustrating to say the least.

I dont see how any download manager can work with this set up short of using something like Power Automate or some other scripting tool to mimic clicking of the download buttons. Far more work than Im willing to do and I guess I'll just have to click download links one at a time in the background while Im working on other things.

What connection speed do you have? Try it with a 20mbps connection. I have 3 internet connections, its the same on all 3.

Also reddit and even these forums contain many posts of users describing exactly both of the same issues I have described.

Something is broken in SLRs bandwidth management code that causes these issues on slower connections. I dont have these issues with any other sites I use. Also there are notes from users that SLR made changes to their code in summer 2021 which have either created this, or made it worse.

midorijin Yeah. That makes all the difference. Its pretty clear that the code SLR is using has some serious issues with slower connections given that I can find posts of the exact same problem by others here and on reddit.

Your connection is at least 50x faster than mine.

Its not my provider. I provided links of users both in these forums as well as reddit who have exactly the same issue.

I also have 3 separate internet providers. One from the telco, one from the cable company, and one from 4G. They are independent companies from each other, each with independent infrastructure as well as independent out of country pipes.

It happens on all of them. The only commonality here is that Im in a remote location, so my connections vary from 10 to 35mbps and many times of day I cannot peak them at all. So 20 that i quoted is an average.

As you can imagine, streaming is even worse most times... thus, those of us with such connections have all the more need for downloads and its one of the reasons I chose SLR as some sites dont even support downloads at all.

FWIW - My background is web development and networking with about 40 years IT experience. I've been doing web dev since we had to compile NCSA Mosaic ourselves (first web browser) in the early to mid 90s and have been both building networks and programming network software from even the pre web days, and even pre gopher days when we had to do the code on mainframes because they were the only machines connected to the internet at the time.

I appreciate your help, but SLR clearly has an issue here in their code and it appears related to a change made in summer 2021.

jsmith579111 its the same on all 3.

Yes, because the issue is at your system level. Don't misunderstand me. I'm not saying there is something wrong with your system. It's about how it's handled by the system.

I do often queue a lot of downloads from SLR yes. The screenshot with the simultanious downloads in the other thread was just per illustration that SLR does allow simultaneous file downloads (streams). You have to keep the amount of connections reasonable too. 15 seems to work just fine on SLR. Not 15 per file, but 15 combined over all files actively downloading from SLR. I'd also recommend to keep it at least at 3 connections per file.

Maybe having 3 internet connections, if all connected at the same time, is somehow making things worse by the system trying to load-balance.

There are VPN services that allow you to combine multiple internet connections into one.

The problem is SLRs code.

1) I am not the only user who has this issue. Please see previous links I posted.
2) I only use one connection at a time with SLR. I only download one at a time, because of a separate problem with SLR and slower connections, also detailed by several users in links above.
3) Based on reddit threads, this seems to have appeared with a change made by SLR in mid summer 2021.
4) I do not have this issue with other sites.

SLR code is not working properly with slower connections. That is the issue. I would bet if you set up a connection speed limiter and tested it, you would see what I and others have been reporting.

The second poster in this thread (who is not me) reported this in 2020.

1. I know, the cause and solution is the same however for all of them.
2. Same thing
3. This is something that's been going on for as long I can remember. SLR also has been a streaming service since as long I can remember.
4. Other sites are not streaming the files. As in, their servers are not set up as a streaming service. I know you can stream many of them too. Things just work way different between a file hosting and streaming service. A streaming service has to be able to break things down in smaller chunks and handle more simultaneous connections to more users at the same time.

The way the files are encoded is even different if it's meant for streaming. Ever noticed how some videos don't play at all if it's only partially downloaded, and other DO play the parts that are downloaded?

A streaming encoded file you can start playing anywhere in the timeline. Non streaming files will either require you to cache everything from the start to where you are skipping to, or need you to cache a pretty large part at once, if not the entire thing.
