DynamicSkins 1.3.8 — Forge

Fixed

• Fixed a brief ping spike for some nearby players right after someone changed skin. The fast lane for nearby players (about 480 KB/s) could send faster than a viewer's connection could carry, and the queued skin data delayed that viewer's keep-alives (measured on the live server: 26 ms → 370 ms for about 1 s). The fast lane checked only the keep-alive ping, which updates every 15 seconds and cannot see a queue that builds within a second.
  • The server now reads each player's live TCP round-trip time and compares it with the lowest seen on that connection. The fast lane is used only while that connection shows no queue (40 ms or less above normal).
  • When a player's connection is already queued by more than 150 ms (for example while loading chunks), the server stops sending skin data to that player until it drains, for up to 1 second, then continues at the normal rate (about 160 KB/s).
  • Players with clear connections still get skins as fast as in 1.3.7. The uploader is not affected (the measurements showed no ping change for uploaders).
  • Works on Linux servers using the native (epoll) network transport, the default. On other servers delivery behaves as in 1.3.7.

Compatibility

• Server-side change only; network protocol unchanged (version 2). 1.3.2 and newer clients can connect.
