See man swapon, man swapoff, and man mkswap on any Linux ^^^^^^^^^^^^^^^^^ Bullshit. Obviously, you don't know the difference between terms 'swapping' and 'paging'. Swapping means swapping complete process spaces to disk (what bsd does) , whereas paging means putting some fixed size pieces of memory to disk (what linux does). Obviously, the former is slower than the latter. *I* know the difference between swapping and paging, as you put it. However, today, swapping has taken on dual connotation of both swapping and paging, and pure swapping has mostly gone out of style, as with good paging algorithms, it hardly makes sense. Don't be so pedantic -- it's not "bullshit", it's someone without a classical operating systems education... And if you want to get *really* pedantic, you could say that, yes, Linux *does* occasionally swap -- if all the pages of an executable are paged out to disk, then the application is technically swapped out, no? Cool down -- don't be so righteous. michaelkjohnson
