Switching proxy “bumps” the upload speed

[brawaru]

Description

When you switch proxy, you get a huge speed “bump,” means your upload speed is getting higher than it was before you switched the proxy, even if you switched back to the previous proxy. The next file (if there is queue) will be uploading slower than the file when you switched proxy, but you can repeat steps to get “bump” again.

When I say “huge,” I literally mean there is a big difference between standard upload speed and when you “bump” it with proxy switching:

• 13.0 MB file:
  • Standard: 59.90s (avg. 222.23 KB/s.)
  • “Bumped”: 22.54s (avg. 590.59 KB/s.)

~~Still, Telegram upload speeds are pretty bad ;—;~~

Steps to reproduce

1. Start uploading a file
2. Switch proxy

Expected behavior

Speed stays the same or even better, being as if you'd switch the proxies.

Actual behavior

You are getting higher upload speed even if you switch back to the previous proxy.

Configuration

Operating system: Windows 10 Insider (Pro), 10.0.18262

Version of Telegram Desktop: 1.4.4 Beta

~~Used theme:~~

I made a demo video where I show how it exactly works, I also used stopwatch on my phone to show an elapsed upload times in seconds.

and... what's the problem of get better performance? xd

The problem is not getting it without having to switch proxies back and forth.

The problem is still there. Ideally, you should get the same higher speed as when you do the trick with switching proxies. This has nothing to do with proxies themselves, you can toggle proxy on and off and it'll improve uploading speed, rather it's something with uploading mechanism itself.

Still relevant.

With this issue, there isn't an actual proxy involved correct? If there is a proxy involved, then I could see a proxy actually slowing things down. I've noticed since one of the updates, that the "disable proxy" setting is not being honored upon startup. So when opening telegram, it uses the system proxy settings in windows via IE internet options and toggling back and forth makes telegram actually use the settings. So I wonder if this is related to that issue, which someone else reported?

[brawaru]

I don't think it's related to this issue, and yeah, in this issue actual proxy is not involved, it's just that Telegram uploading/downloading speed improves upon switching between any proxies, which I would consider a bug and wish such speeds were the default.

After switching from https://github.com/kotatogram/kotatogram-desktop to TDesktop issue with upload speed became very noticeable. Kotatogram has upload speed boost feature and it's really works, speed ups to 200-300% in comparison with TDesktop.

I wondering why there is no ticket with feature request about boosting upload speed. https://bugs.telegram.org - here I can't find it too.

Try 3.7.6 beta, I can't reproduce it

[brawaru]

Oh, sorry. Yea, I cannot reproduce this either, with introduction of Premium speed got ever so slightly faster and toggling proxy doesn't seem to affect it anymore.

NVM! While testing with switching Telegram proxies became harder due to lack of those (since Russia for example does not block Telegram anymore), actually reconnecting your internet while Telegram is uploading gives you a significant speed boost.

Steps to reproduce:

1. Start uploading a large file.
2. Turn your internet adapter on/off or enable/disable whichever VPN you use (just cause a brief disconnect).
3. Notice file uploading speed.

Expected behaviour: Telegram uploads at best speed from the beginning.

Actual behaviour: Telegram uploads at the worst speed, but will upload significantly faster after reconnecting.

4.2 still have it but not proxy. When I turn off / reconnect my VPN - upload speed is bumps from 3mb to 20mb. But it's still slow (I have 100mb connection), so we need it - https://github.com/telegramdesktop/tdesktop/issues/17272

[Neurotoxin001]

Can you reopen it or I create new? 4.2.1 bumbs upload speed after VPN reconnect

[Neurotoxin001]

4.2.4 bumps upload speed after switching proxy too, lol

[Neurotoxin001]

4.4.1 issue is still here. You think it's ok that you don't fix speed issues for more than 4 years?

test on 5.0.1

[Neurotoxin001]

Uploading speed is now much better, but sometimes it's getting slow and switching proxy still “bumps” the upload speed

With only the information that is currently in the issue, we don't have enough information to take action. Please reach out if you have or find the answers we need so that we can investigate further.

Oh it waited for MY response? I can pretty much reproduce this, but it's what @Neurotoxin001 said, the speeds are a lot better now, but switching proxies still bumps the speed even more, esp in cases when for whatever reason speeds drop.
