Meanwhile, I would like to know if anybody here knows of instances when
libxml was asked to parse a file that's approximately, say, 45MB, and
how long it took to parse it. I just need to know if libxml performs
significantly better than 39s/23MB of text.

Assuming this is somehow significant:

xmllint --timing --noout gave me a parsing time of approx 8 seconds for
a 113025049 bytes, deeply structured, indented XML file. Removing
indentation dropped parsing time to nearly 5 seconds. The machine was
a double processor with 2GB of ram:

I don't know what you mean exactly with "parsing", however keep in mind
that XML parsing does _NOT_ parse the attributes. They remain as plain
UTF8 strings and you have to parse their value by other means.
