while I can see that with 2.5 hours parse time you'd not want to run code two or
three times just to compare, had hoped for a more precise measure than "did not
help much".  a big UK supermarket has the advertising slogan "every little
helps"  :-)  (I'm guessing that there could be other opportunities to improve
that code, in addition to the loop you've shown)

I'll have most of Tuesday to myself, so if you want, post an archive with code
and image(s).  I'm curious, and would be happy to have a look.

(I think #cores and threads in a new computer, even if slightly higher clocked,
won't make much difference wrt single threaded parsing; more RAM might if swap
is used.  hopefully someone will correct me if this assumption is false)
