10gig is there..
After I saw this I went to the site, they have firewalls that go all the way up to 120Gbps of throughput and 300,000+ connections per second. Last time I looked I don't recall seeing anything that could go nearly that fast! That particular high end firewall has 4x10Gbps ports and 40x1Gbps ports.
The lowest end firewall I see with 10gig is the SRX3400 which has 2x10Gbps ports and 32x1Gbps ports
