We have an application that requires us to write information
to memory continually, and then use the swap space on disk
if memory is full. We have set up /dev/wd0b as a swap
device, and have then used:
mount -t mfs -o -s=65536 swap /mnt
to mount an MFS in /mnt. This works fine and we are happy
with it. However, when memory gets full, we want to swap a
large portion (say 8 megs) of information from memory to
disk, thus freeing up 8 megs of memory and meaning that
swapping will not occur very frequently at all.
Is there a way to specify how much info must get swapped to
disk at swap time?
Thanks
Bruce
