I know I can run gjournal w/o the BIO_FLUSH feature, but > that would make any performance results rather worthles, wouldn't it? =46rom my tests BIO_FLUSH doesn't have huge impact on performance (if at all), but I suspect it greatly depends on specific HW. Unfortunately I'm not able to implement BIO_FLUSH to all out storage drivers. Currently BIO_FLUSH is supported by ata(4) (/dev/a[dr]X), da(4) and amr(4). --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
