Thank you all for everything so far. But I am not looking for comparisons. I am looking for stuff that has been written so that people can understand. Let's say this: Multi-threaded SMP architecture capable of executing the kernel in parallel= on multiple processors, and with kernel preemption, allowing high priority= kernel tasks to preempt other kernel activity, reducing latency. This incl= udes a multi-threaded network stack and a multi-threaded virtual memory sub= system. With FreeBSD 6.x, support for a fully parallel VFS allows the UFS f= ile system to run on multiple processors simultaneously, permitting load sh= aring of CPU-intensive I/O optimization. In the real world, that ought to sound more like: FreeBSD includes support for symmetric multiprocessing and multithreading. = This makes the kernel lock down levels of interfaces and buffers, minimizin= g the chance of threads on different processors blocking each other, to giv= e maximum performance on multiprocessor systems.
