> * The 1:1 libthr threading model is now the default.
> * Finer-grained IPC, networking, and scheduler locking.
> * A major focus on optimizing the SMP architecture that was put in
> place during the 5.x and 6.x branches.
>
> Some benchmarks show linear scaling up to 8 CPUs. Many workloads see a
> significant performance improvement with multicore systems.
