How it is possible that swap ussage is 136k and swapped out portion of (in
this case) mysqld process is 1.2g ?
SWAP is just VIRT - RES. It means that 1.2g of the allocated virtual
address space is not resident, but it does not mean that all of it is
written to the swap space, it can also be part of a file based mapping.
OK but where I can find per process data about number of
pages/amout of memory in swap ?
