It sounds as if the swap was working (as the build took a long time, it = didn=E2=80=99t run out of memory). My guess would be that, before the = reboot, something had wired (or, if not, then touched frequently enough = to keep it in core) a large chunk of memory, which forced the swapping. = Swap files are expected to be slower than swap partitions (though if = you=E2=80=99re swapping to a disk, the seek times are likely to dominate = in both cases). I don=E2=80=99t suppose there=E2=80=99s capture of the output of top = from before the reboot? David
