in thread writing the data structure into a XML file (with high performance)

It's not the fastest, but not because (just?) it's beefy. It's because it uses a relatively slow parser. One of the beefiest, XML::LibXML, is also one of the fastest.

XML::Bare is tiny bit faster than XML::LibXML, but it has so many limitations. XML::Fast is suppose to be a bit faster yet, but I expect it has the same limitations.
