Kernel Swapping parameters

These are compared with the 'magic' amount of 2 seconds, without any indication
of where '2' came from.  This seems to be in all USG-derived systems.

Recently we had a customer (with a very slow disk) complaining about the amount
of time his system took, and I put in (just out of curiousity) a hack to vary
these parameters on the fly and I was STAGGERED by the difference.  I got over
a TENFOLD improvement in response time by upping both to 8.

I tried using 6 and 8 for inage and outage for my machine, 
but I didn't get much improvement over the default numbers.
I guess it depends on the specify hardware configurations.
Certainly, if your swapping disk is very slow, any reduction
in process swapping would help.  It might be better to fix
the disk &/| controller &/| driver than to decrease the
swapping frequency, i think.  By the way, did you notice an 
increase in response time for more users? ( I don't have
enough ports in my machine to verify this )
