Swapping has other uses. Swapping rarely used data from main internal memory to free up space for disk cache and read-ahead buffers can improve performance. This is why you can sometimes see swap usage even though you have a gigabyte free.


One situation I was wondering about, was if you had a huge data file. Might it be easier to load the entire file into memory (real & virtual) and process it there, than by reading & writing blocks of the file as necessary?
