If amd64 vs i386 matters on your Atom, you got the wrooooong hw.
Why did you buy a slow computer THEN suddenly worry about small
performance differences?
You need to replace that hardware before putting it into production with
something you know will do the job.
Many seem to think tuning a firewall is like drag racing, where every 1%
might be the difference between winning and losing. It isn't. It is
like driving in traffic -- you can't go faster than any of a number of
potential bottlenecks (speed limit [network adapters], car in front of
you [other users], police [ISP bandwidth], etc.). You adjust the things
that actually slow you down, and fiddling with anything else is 100%
wasted effort. It doesn't matter if your CPU is 90% idle or 80% idle,
the packets are all getting through. If it is 10% idle vs. 20% idle,
you have the wrong hardware and are having (or soon will have) problems.
