We have a proprietary OS, which is a variant of FreeBSD 2.x and has extensive changes to protocol stack. We are planning to migrate to the latest FreeBSD like 4.x or 5.x to get multiprocessor support. So I am trying to evaluate these options. How good the network protocol stack takes advantages of the multi processor in 5.x ? What parallelizing paradigm (Connection level parallelism / Packet = level parallelism / processor per message / predictable parallel protocol processing) is implemented for network protocol stack (like TCP/IP) in BSD 5.x ? Are there any benchmarks on the performance analysis of network = protocol stack on multiprocessor system ? Thanks, VBabu
