## Known Considerations
### Current Limitations
- Storage overhead is significant (286%) - this is inherent to VSA
- Ingestion is slower than extraction - by design (encoding vs algebraic operations)
- Large-scale testing (20GB+) requires dedicated resources
### Optimization Opportunities
- GPU acceleration framework is ready for CUDA/OpenCL implementation
- Parallel ingestion possible with threading refinement
- Streaming mode could reduce memory footprint
- Compression on engram files could reduce storage
### Future Capabilities
- GPU-accelerated cosine distance calculations
- Distributed processing across multiple nodes
- Incremental update mechanisms
- Real-time ingestion with minimal latency
