For now, I set up 16G amd64 with ZFSv28, 4k recordsize and no other particular tuning, roundrobin lagg on 2 ems, mtu 9000. There are 4 WD RE3 1T disks as AHCI, on raid10 ZFS config. However, performance seems to be far from optimal (more deep testing is due, but at least average latency is too far, more than 100 ms). Local tests from zvol's (yes, that's not directly comparable but still) provide more than 500 MB/s on single/dual thread. Thanks in advance! -- Sincerely, D.Marck [DM5020, MCK-RIPE, DM3-RIPN] [ FreeBSD committer: marck@FreeBSD.org ] ------------------------------------------------------------------------ *** Dmitry Morozovsky --- D.Marck --- Wild Woozle --- marck@rinet.ru *** ------------------------------------------------------------------------
