Hi there.

Now I'm using FreeBSD 9 without swap, and without additional swap -
related configurations.

Ξ ~ → gpart show
=>       34  234441581  ada0  GPT  (111G)
         34        128     1  freebsd-boot  (64k)
        162  234441453     2  freebsd-zfs  (111G)

Ξ ~ → pstat -T
3857/12328 files
0M/0M swap space

And all work perfectly or that seems to me :).
My working machine is ThinkPad T61 with 4G ram.
I'm typically desktop user.
And the question is:
Does it correct to use freebsd like this? Or I need specific setup?

Option NO_SWAPPING if I understand right not for this purpose.
Sysctl vm.swap_enabled=0 seems to be useful.
