Latency Management.

Optimize multi-layer stack performance through parallelization and intelligent selection.

LATENCY OPTIMIZATION

Multi-layer stacks compound latency. If each of 4 layers takes 100ms sequentially, total latency is 400ms—unacceptable for interactive flows. Optimization is essential.

Parallelization is the primary optimization. Execute independent layers simultaneously; total latency becomes the maximum of individual latencies, not the sum. Requires careful dependency analysis.

Selective layer execution reduces unnecessary work. Low-risk users may not need all layers; high-risk actions may require additional layers. Build adaptive layer selection based on context.

100ms

Single Layer

Baseline latency for individual layer execution. Target for acceptable UX.

150ms

Parallel Stack

4 layers parallel execution. Limited by slowest layer plus orchestration overhead.

400ms

Sequential Stack

4 layers sequential execution. Unacceptable for interactive flows.
