So, if your working set (files, application memory, etc) fits in memory, how does swap not introduce latency?

Some pages of memory in your working set may be rarely used. If so, then allocating physical pages of memory may be a waste. The kernel may be able to get better performance by using those pages for the disk cache - decreasing latency by hitting the disk less.
