AzureFeed 'dotnetcli.azureedge.net/dotnet' in dotnet-install script was too slow in China #7239

Open RayWangQvQ opened 2 years ago

RayWangQvQ commented 2 years ago

As dotnet/install-scripts#236 , I tried to install sdk with version 5.0.404, it was slow too. So I guss, it is not about latest.version.

Here are the cmds:

./dotnet-install.sh --version 5.0.404
./dotnet-install.sh --version 6.0.100

The script showed their download urls(sdk v5.0 and v6.0):

https://dotnetcli.azureedge.net/dotnet/Sdk/5.0.404/dotnet-sdk-5.0.404-linux-musl-x64.tar.gz
https://dotnetcli.azureedge.net/dotnet/Sdk/6.0.100/dotnet-sdk-6.0.100-linux-musl-x64.tar.gz

Here is my speed in browser:

For current situation, it is always blocked and finally failed when I use the scripts in linux server in China.

Would you like please to check agin and resolve it, THX!

Hi @RayWangQvQ, Thank you for the issue. We are investigating this and I will get back to you once we have a better understanding of the situation.

bekir-ozturk commented 2 years ago

Hi @RayWangQvQ, According to my investigations, there doesn't seem to be any special handling on our side to cause such slowness in China. Can you check if you are behind a firewall or VPN? Your ISP may also be limiting your downloads. Can you test your download speed with other sites and share the results? This would help us understand if this is specific to Microsoft sources.

In the same server and same time:

bekir-ozturk commented 2 years ago

Thanks @RayWangQvQ. Interesting. This doesn't seem to be related to install scripts, since you are getting the same speed issues in your browser as well. So I will move this issue to 'dotnet/core' repo to be re-triaged.

@rbhanda who should look into this?

rbhanda commented 2 years ago

Hi @mairaw this doesn't look like something we control. As @bekir-ozturk mentioned, this is not related to the install scripts.

But who owns the hosting site?

I'm also located in China but cannot reproduce your issue. This may be a networking issue of your ISP (aliyun).

But who owns the hosting site?

The packages are delivered by a CDN.

Are you using VPN or other similar magical things?

I don't think it is aliyun cloud's problem, because it is also slow when I download it in my local PC. As the picture in my first comment, it is my local browser(Edge), and the problem remains.

No.

I'm in Korea, but I'm experiencing slow downloading, too. Usually, it's fast and I think it seems to slow down every time updates are distributed. Visual Studio Installer also stuck in checking updates forever whenever this happened.

I put the traceroute results in Korea below for your reference:

this is a cdn error,we can use vscode.cdn.azure.cn host download vs code exe Example Used: https://az764295.vo.msecnd.net/stable/d045a5eda657f4d7b676dedbfa7aab8207f8a075/VSCode-darwin-universal.zip

replace

https://vscode.cdn.azure.cn/stable/d045a5eda657f4d7b676dedbfa7aab8207f8a075/VSCode-darwin-universal.zip this url use cdn node in china，is fast

the same issues like packages.microsoft.com is to lower in chinese https://github.com/tuna/issues/issues/335 https://github.com/dotnet/core/issues/2882

So can we use the same solution as the VScode team？for example use dotnet.cdn.azure.cn？ From the domain name （azureedge.net,azure.cn） perspective, these two urls belong to the same department azure

VAllens commented 7 months ago

Any progress on this? It's occasionally slow and occasionally fast, which seems to CDN cause problems.

jingliancui commented 1 month ago

I also occurred this very slow when config the maui env, I also report to vs feedback. But any progress on this? I also in China. https://developercommunity.visualstudio.com/t/Download-dotnet-sdk-is-very-slow-in-Chin/10704045
