OS choice for an edge router

[Kirc Gover]

We are in the stage of planning and research for a commercial development of an edge router that will be based mostly on OpenSource software. I would like to solicit for information and recommendation if FreeBSD is a suitable OS. The router is expected to withstand forwarding of sustained traffic from 10Mbps to 1Gbps and maybe more than that. Are there any known limitations of FreeBSD in terms of architecture and performance? Can I just take out a FreeBSD as is and put it with the hardware without any specific or major refinements in its code? I'm  very much concerned with its capability in forwarding heavy sustained traffic. Packet loss should be at minimum and critical userland processes should working normally  even under heavy load. Are there any known specific limitations of FreeBSD? I have browsed through the archives and found a lot of hangups, deadlocks and freeze issues. What is the usual or minimum hardware requirement? Is soekris box enough, or dual core or ASIC
 based platforms? I'm aware that there are so many FreeBSD based routers and network based devices in the market. Is this a way to go over realtime and embedded OS such as VxWorks and others (mostly commercial) without putting the licensing cost in picture? I really appreciate any help, suggestions and recommendations. More power to FreeBSD!
 
 Thanks
