Perhaps you'd like to check the mailing list archives. In a nutshell, softupdates on FreeBSD gives very near the same performance as an async mount, and gives you =much= better filesystem security. How that compares to various Linux filesystems, I don't really know. Nor do I really care. -crl -- Chad R.
