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. 2c, Adrian
