Thanks for the extra information. Very useful.

By "same PC" to run a test under Windows vs. Linux, I meant classic dual boot and GRUB as I have

I'd totally forgotten that 20 years ago I rushed out to buy a Unix magazine (with free CD-ROM attached!) containing GRUB, which I installed on my good old Dell PC to happily dual boot Windows and Linux for several years. :)

I've felt a bit overwhelmed recently with the massive changes in the virtualization arena. AFAICT, WSL2 adds about 5% overhead compared to running Linux natively, so your dual booting performance figures (in theory) should be more accurate than mine. Even with the 5% WSL2 overhead, llil2grt runs slightly faster on Linux on my PC.

I'm clueless why this PC is slow with Windows.

I'm clueless why my C++ program runs slightly faster on Ubuntu, while my Perl program runs slightly slower (timings here). :)
