One of the all time problems which exists in any operating system which uses virtual memory, is memory fragmentation. In this video I explore what it is, how the Linux kernel attempts to minimize it, and what tools you can use to monitor it. I will answer the question do you need swap, if so how much swap?, swapfile vs swap partition?
