Do you come from a System V.3 background? The disk cache is managed dynamically by the virtual memory system. If you're interested, start the program top (there's a man page). >>> And second, if it is, how does one _do_ this nondestructively? > > This still stands.

There's no way to influence it externally short of rewriting the virtual memory system, and I can't think of any reason to do that. FreeBSD has one of the best virtual memory systems you will find anywhere. Greg To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
