Memory Management
The Ellemment Stack implements efficient memory management strategies for optimal application performance.
Memory Configuration
Default Setup
- Single instance with 256MB base memory
- 512MB swap file allocation
- Optimized for initial deployments
- Scalable as needed
Swap Configuration
Configure swap size in fly.toml:
[mounts] .swap_size_mb = 512
Benefits of swap configuration:
- Prevents out-of-memory crashes
- Handles memory spikes gracefully
- Improves application stability
- Cost-effective resource usage
Memory Scaling
Increasing Memory
Use Fly.io's scale command for memory adjustments:
fly scale memory [amount]
Available memory sizes:
- 256MB (default)
- 512MB
- 1GB
- 2GB
- 4GB+
Memory Monitoring
Track memory usage through:
- Application metrics
- System monitoring
- Performance logs
- Resource utilization
Best Practices
Memory Optimization
- Monitor usage patterns
- Adjust swap based on needs
- Scale memory gradually
- Profile application performance
Resource Management
- Regular monitoring
- Proactive scaling
- Performance benchmarking
- Usage optimization
Performance Considerations
Swap Usage
- Degraded performance over RAM
- Better than application crashes
- Temporary resource overflow
- Cost-effective solution
When to Scale Memory
- Consistent high swap usage
- Performance degradation
- Increased response times
- Regular OOM incidents
Configuration Guide
Memory Sizing
# fly.toml [processes] app_memory_mb = 256
Swap Adjustment
# fly.toml [mounts] .swap_size_mb = 512
Monitoring Setup
# fly.toml [metrics] port = 9091 path = "/metrics"
