Extension details takes a long time to load when using code-server --link

OS/Web Information

• Web Browser: Brave Browser or Safari
• Local OS: MacOs Big Sur
• Remote OS: Ubuntu 20.04.2 LTS (running on GCP with around 80ms of ping to the server)
• Remote Architecture: x86_64
• code-server --version: 3.11.0 4e8cd09ef0412dfc7b148b7639a692e20e4fd6dd

Steps to Reproduce

1. Go to extensions and search for an extension
2. Click on any extension
3. Wait

Expected

The extension should load in a sensible amount of time.

Actual

Takes around 7s every time you click an extension.

Logs

Screenshot from the network tab:

Screenshot from browser’s console:

Running code-server --link -vvv didn’t produce any helpful logs while clicking around in the extensions tab.

Notes

When restarting the server sometimes it shows a blank screen for quite some minutes until it shows anything.

Sometimes I get:

Error while parsing the 'sandbox' attribute: 'allow-downloads' is an invalid sandbox flag.

This issue can be reproduced in VS Code: No

Extensions load in under 0.5s-ish in VS Code.

@code-asher lmk if I can do any extra testing there, happy to help 😄 I’m using it as my daily code editor for work, I don’t have a real need for it other than that I think it’s super cool 😆

(Sorry for the messy writing, I was taking notes here while testing 😅) I’ve read about those issues so I downgraded to 3.9.3, but made no difference. I’m located in Sicily (southern Italy) and the server is running in Frankfurt (europe-west-3). According to gcping.com there’s around 81ms of ping to the region which is more or less what I get if I ping the server from the terminal.

Running it locally in my MacOS also has the same delay, which would indicate a network issue on my side? But everything in the code editor works blazingly fast (and outside of the editor too, like web browsing, downloading stuff, watching youtube). Is this something I can measure?

If I run version 3.9.3 with Docker WITHOUT --link, the extensions’ details load up right away. If I run version 3.11.0 with Docker WITHOUT --link, the extensions’ details do NOT load, like never.

Here’s a short video of the issue running it locally on my Macbook with --link (3.11 this time, couldn’t get it to install an older version, even with the install.sh --version flag). >15s to load is not something I’m used to in this network connection, to be clear

Other notes:

On GCP: Detected an acceptable latency of 5ms On local: Detected an acceptable latency of 76ms
