Detailed Performance Projections
| Subsystem Dimension | Native Bare-Metal | Ubuntu on WSL2 |
|---|---|---|
| GPU DMA & Pinned CUDA Memory | Direct PCIe 5.0 (0.8 μs) | vGPU D3D12 Bridge (+14.2 μs) |
| Filesystem IOPS (High-Throughput) | Direct NVMe (1.2M IOPS) | 9P / VHDX Loopback (420k IOPS) |
| Kernel Interrupt Jitter (Scheduler) | < 4.2 μs (Deterministic) | ~ 85-220 μs (Hyper-V Sliced) |
| Background Daemon Lifecycle | Native systemd (24/7 Persistent) | Host sleep halts micro-VM |
