That is happening. Robert/Kris' (and others) working on parallelising
the network stack all the way up and down. Kip has been working on
dramatically improving TCP connection and packet forward scalability
to support 10GE. This is in part commercially funded work.
The problem with "commercial funding" is that for the most part,
FreeBSD/Linux/etc "mostly work" for most use cases. What you're not
seeing is 100% contribution back from commercial organisations who
have extended FreeBSD (and linux for that matter) in their environment
to fix specific performance constraints. This is finally changing and
stuff is being pushed back into the public tree.
