"Solaris ZFS жутко медленный под NFS"

Сообщение от Urgen on 29-Окт-08, 21:31

Поставил свежескачанную солярку (ОпенСолярис), решил побаловаться могуществом ZFS'a. Только расшарил под NFS'ом разделы и... жесть! Скорость записи 30Кил/сек, чтения правда поболе 7-8Мб/сек, но что ж это такое?!?! Делаю scp и имею на гигабитном линке 30Мб/сек без всяких вопросов! расшаривал и zfs set sharenfs и share -F nfs - одинаково. Что бы это могло значить? Подскажите, камрады?

Могуществом надо не баловаться, а благоговенно восхищаться :) А если расшарить по NFS не ZFS, а старую UFS - лучше будет?

Подскажите, камрады? Попробуй отключить ZIL, - в /etc/system: set zil_disable=1 и перезагрузись. Скажи пожалуйста - поможет или нет!

	Сообщение от Scott Tiger on 31-Окт-08, 15:57
	Так вроде всё нормально. Надеюсь нагрузка шла во время съёма lockstat-а? :) Потрассируй активность (truss-ом или лучше dtruss-ом), какие системные вызовы тормозить будут, потом для этих медленных сисколлов - разбор полётов, что именно внутри тормозит...

	Съездил в отпуск (ну её, эту работу :) ) и приехав обнаружил в ящике новость о свежевышедшей 10-ой солярке 10/08 (не опенсолярис). Ради интереса решил поставить её и, о чудо, данной проблемы сейчас не имею. На том же железе скорость передачи 9МБ/с. Параллельно нашел тред http://communities.vmware.com/message/1080719;jsessionid=8F0... где идентичная проблема объяснилась наличием бага в драйвере интеловой сетевухи. Ссылка с vmware,потому как в принципе, вся эта солярка мной рассматривается в качестве  сетевого хранилища виртуалок. В принципе первоначальный вопрос снят, остался такого плана - полученная скорость в 9МБ/сек под НФС (при скорости передачи файлов через ФТП в 30-40МБ/с) является ли нормальной? То есть имеет смысл что-то дальше тюнить с параметрами ZFS/NFS, или где-то так и должно быть (имею ввиду разницу в скорости передачи данных по протоколам НФС/ФТП)?

	не нужно рассказывать как тормозит NFS. у меня на linux centos52, NFS3 + XFS + Bond Gigabit средняя скорость для гигабитного клиента 35~40МБ/сек.
