The factor determining IPC performance in robot control systems is the synchronization mechanism, not process boundaries. We share a case study achieving 100x improvement from 78-103us with Mutex to 0.74-0.82us with Lock-free.

We measured whether atomic memory ordering could be a performance bottleneck in a 1kHz RT loop on Jetson Orin (Cortex-A78AE). On AArch64, the cost of seq_cst is virtually identical to release/acquire, and the total cost of 25 atomic operations is less than 0.01% of the 1ms budget.
