Небольшая, хорошая статья: https://jessitron.com/2021/01/18/when-costs-are-nonlinear-keep-it-small/ Краткая выдержка: When costs increase nonlinearly with delay or batch size, larger batches are not more efficient. 1. Batch when incremental cost decreases with batch size. 2. Don’t batch when time delay increases the risk. 3. Do not batch for efficiency when costs increase nonlinearly with size.
