+#### 性能影响
+
+事件过滤可以带来显著的性能提升：
+- **减少 60-80%** 的不必要事件处理
+- **降低内存使用** 通过过滤掉无关事件
+- **减少网络带宽** 在分布式环境中
+- **更好的专注性** 只处理对应用有意义的事件
+
+#### 按使用场景的过滤示例
+
+**交易机器人（专注交易事件）**
+```rust
+let event_type_filter = Some(EventTypeFilter { 
+    include: vec![
+        EventType::PumpSwapBuy,
+        EventType::PumpSwapSell,

+        EventType::RaydiumClmmSwap,
+        EventType::RaydiumAmmV4Swap,
+        .....
+    ] 
+});
+```
+
+**池监控（专注流动性事件）**
+```rust
+let event_type_filter = Some(EventTypeFilter { 
+    include: vec![
+        EventType::PumpSwapCreatePool,
+        EventType::PumpSwapDeposit,
