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). :)

• Cygwin (wikipedia) - a Unix-like environment and command-line interface for Microsoft Windows (uses cross-compilers from Mingw-w64 project)

• Re: How do you run Perl on _your_ system? by kcott (2023) - uses Cygwin on Win10 (and Perlbrew)
• Re^6: Object isn't fully affected by the Animate method in Win32::GUI module by dasgar (2024) - the only way to cleanly uninstall and remove cygwin is to reinstall Windows - because there are parts of cygwin that are not removed during uninstall (while "simpler" CygWin utilities that just need a single DLL can be easily removed)
