Description
Description:
When first starting the server, avatars, icons, and images take a while to load. Most noticeably the "#" and online/offline indicators. Additionally you are unable to upload files during this time period, sometimes for even longer periods of time than that.
Steps to reproduce:
- Start server
Expected behavior:
Rocketchat instantly loads, as before
Actual behavior:
Rocketchat takes a long time to fully load icons and images, and you are unable to send images for a few minutes.

- Deployment Method: docker
- Number of Running Instances: 1

Research direction
Start by reproducing the delay after starting Rocket.Chat 3.12.0 with the reported Docker, Ubuntu, and MongoDB setup, then compare image loading and file uploads during startup. Trace the startup path and relevant client/server requests until the cause is identified; done means icons and images load promptly and file uploads work immediately.
