speedsys isn't reliable to me as a benchmark. It too heavily skews due to FPU performance. I need some kinda accurate or at least good benchmark to benchmark a laptop in DOS that isn't speedsys and doesn't look at FPU performance like speedsys does.

Somewhere in my old DOS utils have a Dhrystone + MIPS benchmark app that tests for just CPU speed without the floating point FPU testing part. Useful for testing 286 and 386 and comparing to 486DX for actual non FPU performance.
Will try to find it. I think Dhrystone MIPS 2.1 is a modern version but could be wrong.
You might want to check this site: http://www.roylongbottom.org.uk/dhrystone%20results.htm and

added: There are lots of comparisons of Dhrystone and Mips testing results plus some apps to run the tests. Not sure if any of his app will run on a 286 though...
Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun
ok thanks horun. after reading about dhrystone it may not work either as it said Dhrystone's small code size may fit in the instruction cache of a modern CPU, so that instruction fetch performance is not rigorously tested
i'll test it though
