+#### Performance Impact
+
+Event filtering can provide significant performance improvements:
+- **60-80% reduction** in unnecessary event processing
+- **Lower memory usage** by filtering out irrelevant events
+- **Reduced network bandwidth** in distributed setups
+- **Better focus** on events that matter to your application
+
+#### Filtering Examples by Use Case
+
+**Trading Bot (Focus on Trade Events)**
+```rust

+```

+**Pool Monitoring (Focus on Liquidity Events)**
+```rust
