It looks like someone wrote it a year ago, but it was never added
to phobos:

Wait a minute, since when do we even have a std.xml2? I've
never heard of it and it's not in the Phobos source tree (I
just checked).

interested if you could make a small, self-contained test
program to use
as a benchmark.
The 'test' is just
/////////////////
import std.xml2;
void main()
{
string xmlPath = r"test.xml";
auto document = DocumentBuilder.LoadFile(xmlPath, false,
false);
}
/////////////////
It's xmlp that does all the work (and takes all the time).
I'll see about generating a simple test file, but basically:
50000 top level nodes
each one has 6 child nodes
each node has a single attribute, and the child nodes each
have a short text value.
Parsing the file with DMD 2.057 takes ~25 seconds
Parsing the file with DMD 2.058(Git) takes ~6.1 seconds
Parsing the file with DMD 2.058, with the GC disabled during
the LoadFile call, takes ~2.2 seconds.
For comparison, MSXML6 takes 1.6 seconds to load the same file.
