Protocol for swap install of files
When reaching the limit of physical memory, enter /sbin swapon -a.
What protocol exists for the entry of data into swap...lifo...fifo ...?
What data enters swap, already installed or newly installed?

Re: Protocol for swap install of files
generally stuff that's swapped first is stuff thats been sitting in memory unused for a while.

Re: Protocol for swap install of files
Interesting, iphitus.
In my actual case, everything in Arch is in memory, Live Larch and that means it is categorized in various locations, opt, etc, var, etc.
What determines the modus operandi for the exodus to swap?
The data entering is one large GB file, contiguous data...video.

not sure how filesystems in ram are dealt with in terms of swap, or even if they are swapped. I suspect that kswapd doesnt discriminate or even know what things are taking up ram, it just swaps pages of ram that havnt been used, from certain zones of memory irrelevant of what they are.

Re: Protocol for swap install of files
Iphitus;
Since the new data hasn't been used, maybe it is first candidate 
I surmise that the new input ends up entiely in physical memory, bumping the old segments into swap.
After finishing utilizing the new data it would seem that in order to restore the swap data to physical memory it might be necessary , after deleting the new data, to reboot the system.
Is the swap data withdrawn to physical memory even though it rests comfortably in swap?
