Both results used to be compareble, so I guess something has affected your second result

Hmm, interesting, I run that benchmark on my ThinkPad T470 with i5-7300U, and got these (comparable) results.

D1:
Microseconds 1 loop: 3.52
Dhrystones / second: 284444
VAX MIPS rating: 161.89

D2:
Microseconds 1 loop: 3.60
Dhrystones / second: 277657
VAX MIPS rating: 158.03

I'll try that once again on my main PC at home, but I run that D2 test multiple times yesterday, and always got the same results.

maybe check power saving options
or leave dosbox running for a while to give some time to warm cpu up ;)
check cpu stats in task manager

Alright, I don't know why, but I rerun that benchmark, and I got comparable result... Or, exactly the same one lol... I don't know, what shenanigans possessed my PC yesterday :D

On both machines I run benchmarks with cycles=max.
