Interestingly, just got windows 7 installed on a usb stick with the windows based zfs recovery tool... now scrubs and resilvers report around 70MB/s on all versions of FreeBSD I have tried (9.3 thru 13-CURRENT), indeed even on my own version with the Broadcom native SAS driver replacing the FreeBSD one... Results are immediately different.. it *says* it’s using 1.6/1.7 cores, ~2G Ram and getting a solid 384MBps (yes B not b) with 100% disk io.... that’s a massive difference. This is using the windows 7 (sp1) built in driver... I can only guess that has to be pci bus handling differences or the throughput report is wrong. (Note “solid” it is fluctuating between 381 and 386, but 97% (ish - Ie a guess) of the time at 384) > >> Michelle >> >>> >>> Kind regards, >>> Patrick >>> -- >>> punkt.de GmbH Internet - Dienstleistungen - Beratung >>> Kaiserallee 13a Tel.: 0721 9109-0 Fax: -100 >>> 76133 Karlsruhe i...@punkt.de http://punkt.de >>> AG Mannheim 108285 Gf: Juergen Egeling >>> >> _______________________________________________ >> freebsd-stable@freebsd.org mailing list >> https://lists.freebsd.org/mailman/listinfo/freebsd-stable >> To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org" > > > -- > Bob Bishop t: +44 (0)118 940 1243 > r...@gid.co.uk m: +44 (0)783 626 4518 > > > > > > _______________________________________________ > freebsd-stable@freebsd.org mailing list > https://lists.freebsd.org/mailman/listinfo/freebsd-stable > To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org" _______________________________________________ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
