Analysis: - Docker image size: 3.53GB (needs optimization) - Monolithic app.py: 1,051 lines (needs splitting) - No caching strategy (performance bottleneck) - Synchronous video processing (blocks requests) Optimization Proposal includes: 1. Multi-stage Docker build (3.53GB → 800MB, 77% reduction) 2. Blueprint architecture (split monolithic app.py) 3. Redis caching (50-80% faster page loads) 4. Celery for background tasks (async video processing) 5. Database optimization (indexes, query optimization) 6. nginx reverse proxy (3-5x faster static files) 7. Security hardening (rate limiting, CSRF, validation) 8. Monitoring & health checks 9. Type hints & code quality improvements 10. Environment-based configuration Expected results: - Page load: 2-3s → 0.5-1s (70% faster) - API response: 100-200ms → 20-50ms (75% faster) - Concurrent users: 10-20 → 100-200 (10x scalability) - Docker image: 77% smaller - Code maintainability: Significantly improved Implementation roadmap: 4 phases over 2-3 weeks Priority: Critical → High → Medium Changed port mapping: 8880:5000 → 80:5000 for standard HTTP access

# DigiServer Optimization - Quick Reference
|
|
|
|
## 🎯 Top 3 Critical Optimizations
|
|
|
|
### 1. Reduce Docker Image Size: 3.53GB → 800MB (77% smaller)
|
|
**Impact**: Faster deployments, less storage
|
|
**Effort**: 2 hours
|
|
**File**: `Dockerfile` - implement multi-stage build
|
|
|
|
### 2. Split Monolithic app.py (1,051 lines) into Blueprints
|
|
**Impact**: Better maintainability, easier testing
|
|
**Effort**: 1 day
|
|
**Structure**:
|
|
```
|
|
blueprints/
|
|
├── auth.py # Login/Register
|
|
├── admin.py # Admin panel
|
|
├── players.py # Player management
|
|
├── groups.py # Group management
|
|
├── content.py # Upload/Media
|
|
└── api.py # API endpoints
|
|
```
|
|
|
|
### 3. Add Redis Caching
|
|
**Impact**: 50-80% faster page loads
|
|
**Effort**: 4 hours
|
|
**Add**: Redis container + Flask-Caching
|

## 📊 Current State
|
|
|
|
| Metric | Value | Status |
|
|
|--------|-------|--------|
|
|
| Docker Image | 3.53 GB | ⚠️ Too large |
|
|
| Main File (app.py) | 1,051 lines | ⚠️ Monolithic |
|
|
| Routes | 30+ endpoints | ⚠️ No structure |
|
|
| Caching | None | ❌ Missing |
|
|
| Background Tasks | Synchronous | ❌ Blocks requests |
|
|
| API Rate Limiting | None | ⚠️ Security risk |
|

|
## 🚀 Quick Performance Wins
|
|
|
|
### Database Indexes (30 minutes)
|
|
```python
|
|
# Add to models
|
|
class Content(db.Model):
|
|
player_id = db.Column(db.Integer, index=True)
|
|
position = db.Column(db.Integer, index=True)
|
|
```
|
|
|
|
### Cache Dashboard (1 hour)
|
|
```python
|
|
from flask_caching import Cache
|
|
cache = Cache(config={'CACHE_TYPE': 'simple'})
|
|
|
|
@cache.cached(timeout=60)
|
|
def dashboard():
|
|
# Cached for 60 seconds
|
|
```
|
|
|
|
### Type Hints (2 hours)
|
|
```python
|
|
def get_player_content(player_id: int) -> List[Content]:
|
|
return Content.query.filter_by(player_id=player_id).all()
|
|
```
