Is your Nostr client slow? You probably have dead relays in your NIP-65 list dragging down your connection.
I wrote a lightweight Python script that fetches your relay list, tests latency for each one in parallel, and tells you exactly which ones to keep and which ones are dead/unreachable.
Takes 3 seconds to run. Run it, clean your list, and enjoy a faster Nostr experience.
