What You'll Learn
- ✓Trace byte ownership across kernel, storage, network, and accelerator paths
- ✓Choose copy avoidance from measured ownership and transformation costs
- ✓Distinguish low-overhead I/O from paths that remove a data copy
- ✓Reason about kernel bypass, RDMA, and GPUDirect through memory topology
- ✓Select serialization formats by lifetime, validation, and schema contracts
- ✓Measure when payload size, NUMA, and page pinning erase the benefit
