Well, unless I am mistaken, a user with normal privileges (non-root) cannot disable paging of memory (using mlock() stuff). So, im not exactly sure what sweep does to gaurantee it is only using physical memory, if that is indeed what it is doing. Perhaps the sweep author can shed some light on what is going on. So yes, as a root user there is definitly a significant difference in how memory is managed if the program utilizes the mlock() system call. It is garaunteed a range of memory will not be swapped out to disk. As a non-root user, I do not believe there is anyway to know what is currently swapped to disk and what is not, so the question you ask then becomes moot. If I am mistaken im sure someone will point it out =) -- Levi Burton http://www.puresimplicity.net/~ldb/
