So again, the first time, put it on your machine

it, I just change libxml2 -- and put comments so I can update.
I have
2-3 of those. libxml2 tries to satisfy the entire world ... you

need to make you happy :-) You might also consider a static

doing that -- safer if customer loads a different version, and
it keeps
loading itself from changing anything, and the program loads
faster,
etc.
Sure, that's where we are now. I am looking for this change to help
other developers, so I'll need to find a solution that can be merged
into libxml2. But thanks for the input.

Can I tell it to not load dtds in the
first
place? Is it loading the dtd for each an every xinclude?
Good catch. It seems that the XInclude engine always parses
included
docs with XML_PARSE_DTDLOAD:
https://git.gnome.org/browse/libxml2/tree/xinclude.c#n450
If you're not using XML catalogs, this will probably cause the
DTD to
be loaded over the network multiple times which could explain
the
slowdown.
Can you try to change the line to
xmlCtxtUseOptions(pctxt, ctxt->parseFlags);
and see if it helps?
