-## Performance Optimizations
-
-### Recent Performance Improvements
-
-The latest version includes significant performance optimizations that dramatically improve event processing throughput:
-
-#### 1. **Batch Processing System**
-- **Event Batching**: Events are now processed in batches (default: 100 events per batch) instead of individually
-- **Reduced Callback Overhead**: Batch processing reduces the number of callback invocations by up to 100x
-- **Improved Throughput**: Significantly higher event processing rates with lower CPU usage
-- **Configurable Batch Size**: Adjustable batch size to balance latency vs throughput
-
-#### 2. **Memory Optimization**
-- **Object Pooling**: `EventMetadataPool` and `TransferDataPool` reduce memory allocations
-- **Pre-allocated Vectors**: `Vec::with_capacity()` for collections to avoid dynamic resizing
-- **Reduced Cloning**: Minimized unnecessary data cloning operations
-- **Memory Usage Monitoring**: Real-time memory usage tracking in performance metrics
-
-#### 3. **Caching System**
-- **Event Parse Cache**: `EventParseCache` avoids redundant transaction parsing
-- **Cache Hit Rate Monitoring**: Track cache effectiveness in performance metrics
-- **Intelligent Cache Management**: Automatic cache size management
-
-#### 4. **Performance Monitoring**
-- **Real-time Metrics**: Built-in performance monitoring with automatic display
-- **Comprehensive Statistics**: Events/second, processing times, memory usage, cache hit rates
-- **Configurable Monitoring**: Enable/disable performance monitoring as needed
-- **Zero Overhead**: Monitoring can be completely disabled for maximum performance
-
-#### 5. **Concurrent Processing**
-- **Async Event Processing**: Non-blocking event handling with `tokio`
-- **Parallel Protocol Parsing**: Multiple protocols parsed concurrently
-- **Optimized Channel Sizes**: Increased channel capacity (5000) to handle high event volumes
-
-### Performance Metrics
-
-The built-in performance monitoring provides detailed insights:
-
-- **Events Processed**: Total number of events processed
-- **Events/Second**: Real-time processing rate (5-second rolling window)
-- **Average Processing Time**: Mean time to process events
-- **Min/Max Processing Time**: Fastest and slowest processing times
-- **Cache Hit Rate**: Percentage of cache hits for event parsing
-- **Memory Usage**: Estimated memory consumption
-
-### Configuration Options
-
-```rust
-// Performance monitoring configuration
-let grpc = YellowstoneGrpc::new_with_config(
-    endpoint,
-    x_token,
-    true,  // enable performance monitoring
-)?;
-
-// Batch processing is automatically enabled with optimal settings
-// Batch size: 100 events
-// Batch timeout: 10ms
-// Channel size: 5000
-```
-
-## Performance Considerations
-
-1. **Connection Management**: Properly handle connection lifecycle and reconnection
-2. **Event Filtering**: Use protocol filtering to reduce unnecessary event processing
-3. **Memory Management**: Implement proper cleanup for long-running streams
-4. **Error Handling**: Robust error handling for network issues and service disruptions
-5. **Batch Processing**: Leverage batch processing for high-throughput scenarios
-6. **Performance Monitoring**: Use built-in metrics to optimize your application

-
-### Performance Tuning
-
-```rust
-// Runtime performance monitoring control
-grpc.set_enable_metrics(true).await;   // Enable monitoring
-grpc.set_enable_metrics(false).await;  // Disable monitoring
-
-// Get current performance metrics
-let metrics = grpc.get_metrics().await;

-// Manual performance metrics display
-grpc.print_metrics().await;
