Security vs Performance Tradeoff Analysis

Current Implementation

1. TLS Configuration (Line 139-142)

   • Security: Strong (TLS 1.3, AES256-GCM)
   • Performance Impact: ~50ms overhead

2. RBAC Caching (Lines 50-53)

   • Security: Slight delay in permission revocation
   • Performance Benefit: ~100ms improvement

3. Audit Logging (Lines 86-110)

   • Security: Critical for compliance
   • Performance Impact: ~75ms per operation

Recommended Optimizations

1. Increase RBAC Cache Size (Line 50)

   • Change maxsize from 1024 to 4096
   • Expected improvement: 5-10ms

2. Async Audit Logging

   • Queue logs for background processing
   • Expected improvement: 50ms

3. Cipher Suite Optimization

   • Consider CHACHA20 first (better mobile performance)
   • Expected improvement: 10-15ms

Expected Results

Optimization	Security Impact	Performance Gain
Larger Cache	Minimal	5-10ms
Async Logging	None	50ms
Cipher Change	None	10-15ms
Total	Minimal	65-75ms
