There are two memory managing processes paging and swapping and they are very different. In a very simple term, when your system is running low in memory, the paging process kicks in first. It scans and releases free memory pages. As long as the paging mechanism can release enough memory for subsequent programs and processes to use, there will be no swapping. Swap will only happen when the page scan can't or not fast enough to release memory and the active process has to be swapped out to make room for subsequent processes. When swap happens, your system will be really sloooooooow.
