I had a look at the vmstat. The highest memory segment had all its inactive pages swapped out, but all the other segments had almost only inactive pages still in. I fixed the pageing out in gnumach, to select inactive pages from all segments before looking at activate pages. I believe that can help a lot when the last segment is small (and thus all the swapping happens there with almost only active pages...) Samuel
