In my experience, almost all Linux systems use some swap at every time. Memory allocated but not used by its process tend to go out to swap. At the same time, the free memory is usally also very low. Memory not in use is memory to no use. Instead the Linux kernel uses rather much RAM for buff/cache for making local and remote disk accesses faster. regards Henrik
