Lousy ZFS performance on D945GSEJT Hello,
I have installed OpenSolaris 2009/06 on D945GSEJT see [1]: - Intel Atom CPU N270 1.6Ghz (32Bit) - Intel Mobile 945GSE Express Chipset - Intel 82945GSE Graphics and Memory Controller Hub (GMCH) - Intel 82801GBM I/O Controller Hub (ICH7-M) - Realtek 8111DL Gigabit Ethernet Controller - 2 Gb Ram DDR2 533 Mhz - 1TB Western Digital Caviar Green (WD10EADS) And followed an Article on heise [2] to setup a CIFS share. But actually I’m receiving bad file system performance (ZFS) on my CIFS share when accessing from Windows Vista [b](16Mb/s write and 6,7Mb/s read)[/b] on Gigabit Ethernet. The question is now, is that low performance expected on that HW? CPU and RAM usage are looking fairly ok during file transfer. Is it possible to substantially improve by SW configuration? How? Which else HW with low power usage could be recommended for better performance? Would have the ZOTAC ION ITX A [3] better performance and is it supported? I doubt it is not because of the Ethernet chip RTL8211 CL see Manuel [4]! Just as Note: With FreeNas based on FreeBSD I received with UFS file system 30Mb/s write and 40Mb/s read and with ZFS 9Mb/s write and 6,5Mb/s read) Best regards, Oliver [1] D945GSEJT Documentation http://download.intel.com/support/motherboards/desktop/d945gsejt/sb/e62862001us.pdf [3] NAS on OpenSolaris http://www.heise.de/open/OpenSolaris-als-Fileserver--/artikel/119995 [3]Zotac ION ITX A Brochure http://www.zotac.com/httpdocs/brochures/mb/ZOTAC-ION-ITX_v3.pdf [4] Zotac ION ITX A Manual http://www.zotac.com/index.php?option=com_docman&task=doc_download&gid=461&Itemid=506 -- This message posted from opensolaris.org _______________________________________________ perf-discuss mailing list perf-discuss@opensolaris.org
