My first question is how many performance counters Xeon has? Some manual says 18, some says 4 for Non-HT Xeon and 8 for HT Xeon.
My second question is how many performance counters VTune uses on Xeon? It seems VTune only uses 2 of them, why not use all of them? The more counters, the less iterations, right?
Please shed some light,
