Memory Management Best Practices
- Use dynamic memory allocation
- Enable memory ballooning
- Configure memory reservations
- Monitor memory pressure
- Implement memory limits
Performance Optimization Tips
Key Considerations
- Memory Overcommitment: Don't exceed 80% total allocation
- Host Reserved Memory: Keep 4-8GB for host OS
- Memory Speed: Higher frequencies benefit VM performance
- ECC Memory: Recommended for critical workloads
Common Memory Issues
- Memory ballooning excessive activity
- Host memory swapping
- VM memory fragmentation
- Memory contention between VMs
