JF>>> тестам небольшой,

Конечно, это не регулярная нагрузка.
Потестил на запись утилиткой xdd по 2 Gb файликами по 3 прохода с разным размером блока на двух разных серверах FreeBSD и с разными файловыми системами.
Конечно, это сравнение еврея с батареей, но всё ж интересно.
1. Hовый сервер - относительно новый(3-летний) с FreeBSD 8.4 UFS2 + gjournal, 4Gb RAM. Диски SAS в железном 6 рейде.
2. Старый сервер - ископаемый мамонт P3 800Mhz с FreeBSD 10, 1300Mb RAM с ZFS mirror. Диски SCSI на древнем AIC.
Второй тест с размером блока 4096 на старом серваке выполнялся... не быстро
Тем неменее, эта ZFS в сравнении с UFS2+gjournal - ну просто летает, однако L)
