fyi, here's another hw.ata.wc=1 vs hw.ata.wc=0 comparison: 4.3-RELEASE install, ASUS A7V, 800mhz, hw.ata.wc=0, express install +all, 60gig wd-600b udma100 drive, partitioned as: / 8192m swap 1024m /xtra 48023m installed from 52x cdrom. install time: 27minutes, 38 seconds (1658 seconds). a modified 4.3-RELEASE install iso (modified by replacing /floppies/boot.flp loader.rc/support.4th and adding a loader.conf, setting hw.ata.wc=1) file, written to cd. same partition, same install (express + all) install time: 8minutes, 59 seconds ( 539 seconds) 4.3-with-wc=1 / 4.3-with-wc=0 : 3.07x in both installation cases both filesystems were newfs'd, but the speed difference is evident everywhere during the install. i would urge the FreeBSD lords to consider mr. silbersack's proposal of either remaking hw.ata.wc=1 the default, or at least, consider making this the default for the base install. perhaps something analagous to the security settings (reliability settings) would be as reasonable paradigm ? thanks! -elh To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
