Clear and concise description of the problem

Currently, Anytype’s file transmission heavily relies on the UDP protocol. When the UDP transmission quality is poor — for example, due to cross-province QoS (Quality of Service) restrictions or when certain cloud bandwidth providers disable UDP to prevent DDoS attacks — the file transfer speed can drastically decrease. After numerous self-hosted deployment troubleshooting sessions, I’ve concluded that poor UDP transmission quality severely impacts Anytype’s file upload and download speeds. When I disabled UDP and used TCP exclusively, the transfer speed became unbearably slow.

I believe we should make better use of the TCP protocol for transmission, as it remains the primary communication protocol for cloud servers. While the issue isn’t as noticeable with plain text or smaller images, it becomes painfully slow when dealing with files over 100 MB, especially when uploading files via mobile. I suggest that we should optimize TCP transmission, at least for attachments within the notes.
