Operating Systems Linux Swap memory issue Post 302892856 by jlliagre on Saturday 15th of March 2014 03:56:51 AM

If the CPU is fully utilized, the performance slow down linearily with the extra load.
If the RAM is fully utilized, SWAP will start to be used. The performance might slow down much more intensively with the extra load, but this will really depend on the active set. There are situations where the performance won't be significantly hurt.
If the SWAP if fully utilized, applications will randomly crash.

There is a common misconception that having a large SWAP area has an adverse effect on performance. This is incorrect, having too little RAM is a serious cause of performance issues. Having too large a swap is a safe configuration.

SWAP-OFFSET(8)							    swap-offset 						    SWAP-OFFSET(8)

NAME
swap-offset - program to calculate the offset of a swap file in a partition SYNOPSIS
swap-offset [<swap_file>] DESCRIPTION
This manual page documents briefly the swap-offset. This manual page was written for the Debian(TM) distribution because the original program does not have a manual page. The programs s2disk and s2both can be used to save the state of the whole system to a swap partition or file and power off or suspend your system. After restarting your system it will be put back in the exact system state you left it (this is sometimes called hibernation). In the case of using a swap file you will have to specify the location of the swap file's header as the offset from the beginning of the partition that contains the swap file. The swap-offset utility can be used to determine this value. SEE ALSO
uswsusp.conf(8), s2disk(8) For more information see the HOWTO and the README AUTHOR
