I can confirm the premium account on a Linux version has 10 mbs as well.
Same issue. Here is my report.
Steps to reproduce
- Try to download video https://t.me/dvachannel/82385 or https://t.me/dvachannel/74593 and look at the download speed
- Try to download file https://t.me/dsd_music/9442 (link is dead, try it https://t.me/rand2ch/13759) and look at the download speed
- Files is downloading faster. Files is ~80mbps and videos is ~25-35mbps.
Telegram for iOS is downloading files at the maximum speed even without Premium. Maybe because basic speed limit is 100mbps and I have that speed from my provider. And Premium removes that limit.
1 video - Tdesktop premium.

Preston (TDesktop developer) says it's because of streaming system: https://t.me/kepka_support/107450
With video, there is a very complicated logic there due to streaming :( Non-streaming ones should be downloaded identically to files.
But when I disable streaming by typing videoplayer
in settings - nothing changed:
Streaming off

I really think this must be №1 issue on the developer's to-do list. If only because the promised function from the premium does not work.

Telegram Desktop 4.0.1, Windows 10
@aliforever Can you please confirm that the speed when downloading a file (like https://t.me/dsd_music/9442) is better than when downloading a video file? Your original report (video confirmation where you've recorded the slow download speed) is used for a video from a bot. Can you try a file and report if there is a difference?
@Neurotoxin001 I think that even with "videoplayer" cheat code it still uses a StreamedFileDownloader for the video file. This is the only difference between a video file download and a file download.
I also asked 2 my friends to download file and video and compare speed and they confirm that file is downloading faster. They using latest Telegram Desktop and Windows 10 too but don't have github accounts to confirm it here.

It took me 64 seconds to download the file (https://t.me/dsd_music/9442 961MB). It would be 15MBps. So I'd say it's 5MBps more than downloading a video.

Are you going to fix it? With upload speed also.
Are you using your client? It's ridiculous. Tdesktop using only 10% of my upload speed.
It's already 2 months after Premium released and this is still not fixed.

Any success with Premium users download speed? Still have 10 Mb/s while getting 1Gb/s from ISP (torrents and all other speed tests show 1Gb/s).
Any success with Premium users download speed?
Unfortunately no. Developers have more important things to do. e.g. animated emoji
Try to download file https://t.me/dsd_music/9442 and look at the download speed
Seems like channel is dead. You can test it here: https://t.me/rand2ch/13759
This issue is still relevant and it's sad that premium feature is not working after 6 months
Still have this problem
Based on my findings the promise of better download speed only applies if you're connecting close to the dc of the file.
If the uploaded file is on Amsterdam DC for example, you'd achieve maximum speed by connecting from an Amsterdam VPS.
I'm not sure what is decreasing the speed between datacenters and locations, but it seems like Telegram doesn't want to share that information
same issue

Is that your maximum speed from internet provider? There is no changes for me. Preston admitted that the problem is in the loader code, and he won't touch it, because he is preparing a version on tdlib (and there is no such problem there, there the speed is maximal, according to the tariff from the provider).
not maximum from internet provider but quite good speed.
Try this alpha on tdlib and you will see difference: https://t.me/kotatochat_ru/195866

But is there same for Macogram ?

Thanks!
upload speed is fixed, but not download
I have telegram premium. Upload speed is 4 mbps for me on PC, downloads are fast. My connection is 1 Gbps
Telegram premium maxing download speed was a false promise unfortunately.
I have a 10GBps server located at NFOrce datacenter, my upload speed to Oracle Cloud buckets are always a lot higher than download speed from Telegram.
