Mit 4 synchronen Workern hielt jede SSE-Verbindung dauerhaft einen ganzen Worker besetzt. 4 offene Browser-Tabs -> alle anderen Requests blockiert -> "Dateien laden dauert ewig". Loesung: gthread worker-class mit 2 Workern x 16 Threads = 32 gleichzeitige Slots. Lang laufende SSE-Streams belegen nur je einen Thread, regulaere Requests laufen unbeeintraechtigt. nginx.example.conf: separater Location-Block fuer /api/sync/events mit proxy_buffering off und 24h Read-Timeout, damit die Events sofort durchkommen und die Verbindung nicht abbricht.
