That's one reason why pagein rates are so much higher than pageout. Don't think that's true for textfiles. I rmeember older *NIXes loaded processes off disk by causing a page fault to read in the binary. I imagine FreeBSD does soemthing similar, The pageins you'd see running cat or more are probably /bin/cat and /usr/bin/more being loaded. -- Using TSO is like kicking a dead whale down the beach. -- S.
