CRITICAL FIX: The previous cached collector architecture still had ZMQ sending in the main event loop, where it could block waiting for RwLock when collectors were writing. This caused the 3-8 second delays you observed. Changes: - Move ZMQ publisher to dedicated std::thread (ZMQ sockets aren't thread-safe) - Use try_read() instead of read() to avoid blocking on write locks - Send previous data if cache is locked by collector - ZMQ now sends every 2s regardless of collector timing - Remove publisher from ZmqHandler (now only handles commands) Architecture: - Collectors: Independent tokio tasks updating shared cache - ZMQ Sender: Dedicated OS thread with its own publisher socket - Main Loop: Only handles commands and notifications This ensures ZMQ transmission is NEVER blocked by slow collectors. Bump version to v0.1.195
