I think all the speed is comming from the make -jN method.
My intel PC has 6 cores. When I run it on windows linux subsystem
it was fastest since it used all 6 cores at same time. On Vbox
it was not fast.
VBOX by default uses one core (even though one can change that).
I do not think RAM is that important here. I see little RAM used
when make4ht is running relatively speaking. make4ht is now running
and using only 150 MB memory, and I have 64 GB ram to use.
So now I am shopping for a new CPU with most cores I can find
as it turns out this is the magic behind speeding up tex4ht
more than anything else.
There are CPU's now with 18 cores and 32 cores. So I need to
start saving money to buy one of these as they get expensive,
but considering the amount of time saved, they are well worth it,
after all, time is money also.
