Sar's pgpgin/s and pgpgout/s tell me that it is paging in/out from/to disk. Yet pswpin/s and pswpout/s are both 0. Swapping and paging are the same thing I believe. pgpgin/out refer to paging, pswpin/out refer to swapping. So I for one am confused.
I guess I could dig through the source but I figured someone might have encountered this disrepency in the past.
