## Performance Profile
### Operation Count (Streaming Mode)
TValue is a 16-byte struct (DateTime + double). Construction and field access are register operations.
| Operation | Count | Cost (cycles) | Subtotal |
| :--- | :---: | :---: | :---: |
| Struct construction (2 fields) | 2 | 1 cy | ~2 cy |
| Field read (Tm or Val) | 1 | 0 cy | ~0 cy |
| IsNaN check on Val | 1 | 1 cy | ~1 cy |
| **Total** | **O(1)** | — | **~3 cy** |
16-byte struct fits in a single XMM register. Zero heap allocation. All operations are register-bound when JIT-promoted.
* **Memory**: 16 bytes per instance.
* **Allocation**: 0 bytes (Stack allocated).
* **Copying**: Cheap (fits in two 64-bit registers).
