I certainly do - whilst I expect Ubuntu to be discernibly faster overall - noting the PI benchmarks often show a 60% - 100% improvement under Linux - WBPP is a bit of a surprise beast - I remember a user with a very high core count system (close to 100 cores) found Windows was the fastest for WBPP - which seems totally unexpected and wrong to me.

I seriously think PixInsight team should pay more care with benchmarks - and organise them by operating system variant and have a benchmark for WBPP too. The Benchmarks as I have said over and over on their forums can tell you if something fundamental is going wrong - but generally Jaun and team tend not to pick this priority - as users are always clamouring for more and improved functionality. My view is you have to keep quality of product high too - else tech debt looms and sooner or later everyone will have to pay the price...

Eventually I do plan to benchmark it - the only real way to know performance is to throw a real stacking workload and trying it across all operating systems!

I would love to be able to review the Thread Optimsiation data file - to see if Windows 10 Pro has different settings under Windows 10 Pro.

If it were easy I could take the Win 11 settings and try it in the Win 10 system - and see if that is better or worse - and the same for Win 10.

I still ponder the Thread Optimsation logic may get the logical core count wrong under Windows 10 in some use cases!
