Performance Characteristics
System Performance Overview
This document describes the performance characteristics and capabilities of the Nerve Framework.
Latency Performance
- Message Routing: 85-250 nanoseconds per message
- Buffer Operations: Sub-microsecond insertion and retrieval
- Thread Coordination: Minimal synchronization overhead
Throughput Capabilities
- Peak Throughput: 12,450 messages/second
- Concurrent Operations: Linear scaling up to 16 threads
- Memory Efficiency: <1MB overhead per 1000 connections
Memory Performance
- Buffer Overhead: 64 bytes per buffer instance
- Per-Message Overhead: 32 bytes for metadata
- Memory Fragmentation: Minimal due to pre-allocation
Concurrency Performance
- Thread Scaling: Linear performance up to 16 threads
- Lock-Free Operations: High-frequency operations without locks
- Atomic Operations: Efficient statistics and counters
