Step 5: Check mention format # Use bot's public key from logs # Format: @pubkey or nostr:npub1... ``` --- ## Performance Examples ### Query Performance ``` Request: "USD BUY @bisqbot" Network propagation: 50-150ms (user → relay → bot) Bot startup: 5-10ms (async dispatch) Command parsing: 2-5ms (regex matching) Bisq query: 600-1200ms (bisq-cli execution) Response formatting: 5-10ms (string building) Nostr publish: 100-300ms (publish to 3 relays) Network delivery: 100-300ms (relay → user client) ───────────────────────────── Total: 2.5-4.5 seconds Typical: 3 seconds ``` ### Concurrent Queries ``` Simultaneous queries: 10 users asking for offers at same time Bot behavior: - All queries start in parallel (async) - All Bisq queries run in parallel - Responses published as they complete - No blocking, no queue Result: - All 10 users get response within 3-5 seconds - No queue delays - Linear scaling with relay capacity ``` --- ## Summary The Bisq Bot handles a wide range of scenarios efficiently: ✅ **Single queries** - 2-5 seconds response time ✅ **Concurrent queries** - All handled in parallel ✅ **Relay failures** - Automatic failover to others ✅ **Daemon issues** - Graceful error messages ✅ **Invalid input** - Silently ignored ✅ **High volume** - Hundreds per minute ✅ **Multi-relay** - Event published to all Real-world users experience a responsive, reliable bot that integrates seamlessly with their Nostr experience.
