Это было умышленное усиление нагрузки с целью получения достоверных
результатов. Кроме того, наличие многих ядер лишь улучшает работу
BFQ, ограничение на 1 ядро нужно для учёта фактора, что BFQ
создаёт дополнительную нагрузку на CPU.
Мораль такая: при любых сильных I/O нагрузках на HDD BFQ весьма
достойно сохраняет отзывчивость системы, т.е. обеспечивает разумные
и честные latency.
Best regards,
