a swap puzzle

hi,i have a puzzle about the swap space used in system(11.11).
when i used swapinfo -atm ,i find that the dev swap used percent is 0%.
but i used sam ->performance monitor->system propertys->mem ,i found the swap used is 1.5Gb.

now my question is that how the 1.5gb come from? thank you.

Re: a swap puzzle

It sounds as though you have pseudoswap (swapmem_on=1) enabled and that 1.5GiB of memory has been reserved for process space. This is entirely normal --- and pseudoswap isn't swap at all; it's just a way to allow a portion physical memory to be counted as process reservation space just as though it were "real" swap space.
If it ain't broke, I can fix that.

What is swap and why does a system need it?
