That is because when all the RAM is being used dynamically by the same program then a swap file is not effective. It is probably something like 1000 times slower (or more) which means that program run times become unacceptable. A swap file only really works for handling memory contention between different programs, or when within a program much of the memory space ace is not being accessed so the working set can be kept in RAM.
