The original Pentium 4 microarchitecture was restricted to a
maximum hyperthreading degree of two. I suspect it's very
unlikely later implementations would go to four. So, the
question would be whether it means you have two physical
processors with two threads each vs. four physical
processors with one thread each.

Good luck.

If you just read the complete output of 'cat /proc/cpuinfo' from
the example box in your OP, you should easily find out, if it's 2
CPU with hyper-threading enabled or 4 without ht enabled.

Good luck
