[LOW][Performance] Startup Time - No Connection Pre-Warming

[filthyrake]

Summary

Servers initialize components sequentially with no connection pre-warming. First request after startup is slow due to SSL handshake, DNS resolution, and initial authentication.

Affected Files

• truenas-mcp/src/http_server.py:124-136 (lifespan startup)
• pfsense-mcp/src/http_pfsense_server.py:124-138 (initialization)

Impact

First request latency:

• DNS: 10-100ms
• TCP handshake: 10-50ms
• TLS handshake: 50-200ms
• Auth: 100-500ms
• Total: 170-850ms vs. subsequent requests at 10-50ms

Recommended Fix

Optional warmup during startup:

# In lifespan startup
if app_settings.warmup_connection:
    try:
        logger.info("Warming up connection...")
        asyncio.create_task(server.client.connect())
    except Exception as e:
        logger.warning(f"Connection warmup failed: {e}")

Trades startup time for improved first-request latency.
