Code review comment for lp:~gz/bzr/remove_monkey_patched_elementtree_escaping_614522

Okay, I'm confused now. Every microbenchmark I could cook up the bzrlib version of the _escape_cdata is actually slower than the original. So, I tried profiling bundle, and sure enough there's an xml escaping function high up in the list, but it's not the etree one:

         502 0 205.1471 16.3189 <C:\Python24\Lib\site-packages\bzrlib\xml8.py>:217(write_inventory)
    +2610268 0 13.1339 8.5832 +<C:\Python24\Lib\site-packages\bzrlib\xml8.py>:94(_encode_and_escape)

So, what command can I run instead to measure how much ripping this code out hurts performance?
