We're running ASL v7.201 on ASG220 appliances with 512MB of RAM each. The one with the added latency is only running firewall with NAT. We don't use any of the spam/virus functions, or any other special options except the NAT FTP application helper.

It could be the IPS that is adding the latency.
Is 12MS really a big deal?

turn everything off except the nat and see what happens. build in the right packet filter rules of course.

i ahve seen forced settings cause issues between servers and switches leading to latency issues...put it on auto negotiate and see if that helps.

Try bridging the firewall and seeing if the latencies change.
ps aux|grep snort
Run ifconfig and look for any errors.
