AFAIK: S=F8ren had the WC off for a while on -current, but a lot of people complained, so he switched it back on (I'm sure he regrets it every time he is reminded about it). So -- including you and me -- there are at least 3 committers which would like to see the WC turned off by default. There are a lot of other people without special @FreeBSD.org privileges which also don't like the actual default (if you can get a look at iX-10/2002 read the "BSD-Softupdates vs. Linux-Journaling" article - the tests for this article where done on SCSI hardware, but this doesn't matter in this case - it explains the interactions of WC, TQ and SO and how they affect the speed of some FS-operations). Maybe we can gain some momentum and restore POLA (in this case the default of going the safe way instead of the fast (but sometimes dangerous) way). Bye, Alexander. --=20 Yes, I've heard of "decaf."
