Win2008R2 System, CPU 2x Xeon E5405. On the bench it is clear that the use of all core (8 pieces), but at the start of operation is set -t option 6 and does not use all cores

Try editing the file configs/benchmark_GEN-{HWID}.json

"CryptoNight": { "NiceHashID": 87, "MinerName": "cryptonight", "BenchmarkSpeed": 170.0, "ExtraLaunchParameters": "", "Skip": false, "LessThreads": 2

Change LessThreads to 0 and restart NiceHash

CryptoNight on CPU performs better when using physical threads instead of using all hyper-threads. The exact number of threads can be set from Extra Launch Parameters to make it automatic set only LessThreads that will determine what is the best thread count for your CPU that will produce most hash rate.

Both tips very nice. Adjusted an i7 for 6 threads instead of 10. Got less cpu usage and faster hash Tks
