That is a *low* end machine!

In general, you want to limit MX_MAXIMUM so the machine doesn't swap.
For really slow machines like yours, you want to lower it even more --
the processor is going to be pegged at 100% while it's scanning a message,
and adding more slaves will not push more messages through.

I'm glad queueing helps!
