From: alexei@taf.ru To: ALT Linux Team development discussions <devel@lists.altlinux.org> Subject: [devel] Ядра 4.19/5.4 и дисковый шедулер Date: Fri, 20 Mar 2020 04:11:50 +0800 (IRKT) Message-ID: <1276556985.742599.1584648710620.JavaMail.zimbra@taf.ru> (raw) Добрый день! Скажите, кто знает, а вот такая картина на ядрах, начиная с 4.19, нормальная?: # cat /sys/block/sda/queue/scheduler [none] bfq при том на 4.9 имеем такую картину: # cat /sys/block/sda/queue/scheduler noop [deadline] Лично у меня такое положение вещей вызвало регрессии производительности при обновлении с p8 на p9, у системы резко вырос iowait. Ситуация выправилась путем принудительного включения bfq на дисках. Вполне вероятно, что упомянутые в Community@ проблемы имеют те же причины.
