As I already wrote in another part of this thread: please explain to me why it should be faster to have a file backed md set up as swap than a dedicated swap partition (because there's at least two more levels of indirection involved). I can clearly see the need for file backed swap in special cases (for example, where you need RAM desperately, for example for a compile, but cannot add another partition to a system), but no matter what, it will never be faster than a swap partition. And that was what the original poster of this sub-thread suggested (and as such, I took it that he was referring to memory-backed mds, because file-backed mds are never faster than "raw" access to a hard-disk). So, I still stand by my first assessment: the idea to use an md as swap is stupid, at least from a performance standpoint. -- Heiko Wundram Product & Application Development _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
