Yes.

It is 8. See the siblings field? cat /proc/cpuinfo shows you all
8 cores, but a lot of it will scroll off your screen.

The 8350 is arranged as two 4-core CPUs sharing the same module.

Specify it.

RAM and disk play a big part, too.

If the irqbalance daemon is not running, you may want to install
it. irqbalance spreads interrupt load over as many CPU cores as
you have, which in most *but not all* situations leads to better
overall performance.
