<pre><code>🚀 Rust MCP Server Performance Analysis
|
||
|
|
==================================================
|
||
|
|
|
||
|
|
📋 Server Parsing Performance:
|
||
|
|
• Sub-millisecond latency across all operations
|
||
|
|
• 0μs average for configuration access
|
||
|
|
|
||
|
|
🤖 AI Status Performance:
|
||
|
|
• AI Status: 0μs avg (10000 iterations)
|
||
|
|
|
||
|
|
💾 Memory Footprint:
|
||
|
|
• ServerConfig size: 80 bytes
|
||
|
|
• Config size: 272 bytes
|
||
|
|
|
||
|
|
✅ Performance Summary:
|
||
|
|
• Server parsing: Sub-millisecond latency
|
||
|
|
• Configuration access: Microsecond latency
|
||
|
|
• Memory efficient: Small struct footprint
|
||
|
|
• Zero-copy string operations where possible
