If i'm in the wrong place, let me know and i'll re-post elsewhere. I just read something very interesting about Linux program execution, and i was wondering how FBSD compares in this respect. "The loading of a binary file into physical memory is not performed by the binary loader under Linux. Rather, the pages of the binary file are mapped into regions of virtual memory. Only when the program tries to access a given page will a page fault result in the loading of that page into physical memory." Does FBSD have a similar mechanism? If not, what advantages/disadvantages does FBSD have? The Linux method seems interesting and quite efficient. -jm To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
