I'm seeing about 600h/sec on an i7-7700
I get 580-630 on an i7 6700 at stock clocks (without locked pages enabled
That's pretty slow. On i5-4570 (all stock, 16Gb ram @ 2 channels, win10, locked pages enabled) it's ~745h/s (without any other load), or ~748h/s after reboot and miner's clean start. Drops to ~550 with regualar web browsing though.
Well, 630 +20% is over 750, +30% is even higher, so I think the results are pretty typical considering that lock pages is not enabled on that particular PC (doesn't have Windows Pro installed, just Home which does not allow locked pages to be set.
