Are you new to mining ? These are khash per thread.
Of course they don't vary with the number of threads ...
If you're using more threads than number of cores your cpu has, mining speed per thread should decrease. That instance has 32 cores, mining speed should max out at 32 threads. But the client reports the exact same speed per thread, even when I stuff 32 threads per core (1024 threads) That makes no sense.
That happens only in the first round when threads are initialized and tested. Leave it running 10 seconds and you'll see that if you have more threads than cores and you keep adding threads then each one starts going slower and the total mining speed does not improve.
