func CPULatencyNs(size int) float64

CPULatencyNs exposes the CPU latency curve for reporting.

func ShouldPreferGPU(size int) (preferGPU bool, ok bool)

ShouldPreferGPU returns whether GPU latency is expected to beat CPU latency. ok indicates whether the decision is backed by empirical GPU data.

type Sample struct {
	Size           int
	CPULatencyNano float64
	GPULatencyNano *float64
	Source         string
}

Sample captures empirical latency measurements for a given collection size.
