Where it's a real win is with the large filesystems. I still don't understand why JFS has any interest over softupdates. Indeed, the papers I've read seem to indicate that, at best, JFS may approach the kind of speed possible with softupdates, and they both allow you to re/boot quickly and with mount times that do not include lengthy fsck. Indeed, Sun paid megabucks to Kirk in order to get a commercial license for softupdates, and yet they already have a built-in JFS that has been freely available since Solaris 2.6. Why would they pay money for something like this if it wasn't better than JFS? So, why should we care about JFS? -- Brad Knowles, <brad.knowles@skynet.be> H4sICIFgXzsCA2RtYS1zaWcAPVHLbsMwDDvXX0H0kkvbfxiwVw8FCmzAzqqj1F4dy7CdBfn7 Kc6wmyGRFEnvvxiWQoCvqI7RSWTcfGXQNqCUAnfIU+AT8OZ/GCNjRVlH0bKpguJkxiITZqes MxwpSucyDJzXxQEUe/ihgXqJXUXwD9ajB6NHonLmNrUSK9nacHQnH097szO74xFXqtlbT3il wMsBz5cnfCR5cEmci0Rj9u/jqBbPeES1I4PeFBXPUIT1XDSOuutFXylzrQvGyboWstCoQZyP dxX4dLx0eauFe1x9puhoi0Ao1omEJo+BZ6XLVNaVpWiKekxN0VK2VMpmAy+Bk7ZV4SO+p1L/ uErNRS/qH2iFU+iNOtbcmVt9N16lfF7tLv9FXNj8AiyNcOi1AQAA To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
