This thing is built like a tank!  This is my first dip into running pfSense, and the question I could not seem to get a straight answer to is "how much throughput is any particular hardware package good for?"This particular box will easily run a full gig as a straight firewall with 4 gigs of RAM.  If you turn on Suricata for IDS/IPS, the CPU is your bottleneck, and this box will run somewhere between 300-500 Mbps depending on your traffic mix.If you really need a full gig, i would suggest finding a box with a CPU that has a benchmark score 2-3 times higher than the Celeron J3160.
