You, Matthew Dillon, were spotted writing this on Thu, May 25, 2000 at 10:57:33AM -0700: > > I don't particularly like to use MFS for 'large' partitions, mainly > because cached data blocks wind up in core memory twice (once in MFS's > memory map, and once in the VM page cache). You've said this several times in threads on MFS during recent months, and I've always wanted to ask: is that a necessary 'feature' of MFS's architecture, or something which could possibly be fixed without too much hard work? For instance, would it be possible to force VM not to cache MFS pages, etc.? -- Anatoly Vorobey, mellon@pobox.com http://pobox.com/~mellon/ "Angels can fly because they take themselves lightly" - G.K.Chesterton To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
