fwiw I did some tests a couple of years back with 
https://launchpad.net/d2-xml on 20 odd megabyte files and found it 
faster than Tango.
Unfortunately that would need some work to test now, as xmlp is 
abandoned and wouldn't build last time I tried it :-(

I also had some success with https://github.com/opticron/kxml, though it 
had some issues with chuffy entity decoding performance.


Also, profiling showed a lot of time spent in the GC, and the recent 
improvements in that area might have changed things by now.
