I think I'd have to agree. I'm really not really seeing how the very 
little swap I am using would cause me to have a ~1.00 load average at 
all times. I'm sure I am not CPU limited, as it's nearly always 100% 
idle (which just makes the 1.00 load average odd if you ask me), and the 
disks are also nearly always idle.

Johnny, is there any chance of going over what you actually changed to 
solve your problem? I've tried messing with the system vm. parameters 
but it hasn't really made any difference.
