I'll make a zip file of the current example document I am working on
to help with this. So any one can see this.

I just need to remove all the \includegraphics from it as they do not
contribute to the issue and to reduce the size of the zip file.

I just need few hrs to do this and will post a link for the zip file.

I bought another PC 3 days ago just for linux and latex use only,
hoping the compile will be much faster than on my windows PC using either
VBox/Linux or cygwin or Windows_10_Linux_subsystem.

(btw, Windows_10_Linux_subsystem is 20% faster than Vbox linux
on same PC. So now I switched to Windows_10_Linux_subsystem instead
of Vbox for Latex compile).

So to compile the file, I copy it from windows PC to Linux
PC on a USB stick and copy the result back to windows.

Native PC using Linux is faster than all the above,
but still too slow compared to using pdflatex or lualatex:

About 3 hrs for htlatex vs. 2-3 minutes lualatex for same file.

90% of the time for htlatex compile is spend in the dvisvgm phase,
processing the DVI file.

Thank you,
