That's because dpkg is known for using (f)sync very heavily. btrfs honours the sync request in all cases, so it's much much slower than ext3, which doesn't.
Hmm, is it really the case with ext3/ext4 (ignoring fsync in some cases)? Sounds like a bug in ext3/ext4 then. Is it documented anywhere where ext3/ext4 would just silently ignore fsync? -- Tomasz Chmielewski http://wpkg.org -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
