Comment 3 for bug 2065904

I wish I remembered what machine and file I generated the previous runtimes with, as the machine/file I chose this time have a much lower ratio between parsing and cloning.

On my Windows laptop under WSL:

====
4.12.3
git checkout 7fb51753743644e23dfb3e7a964d387583dd0bc0
parse HTML, create soup: 56 seconds
copy.copy(): 141 seconds

4.13 - before fix
git checkout 5104c454e47242dfa68e9c6c3b7659e054230017
parse HTML, create soup: 71 seconds
copy.copy(): 150 seconds

4.13 - after fix
git checkout 55c2e34525380ffd83867818169968826a625609
parse HTML, create soup: 71 seconds
copy.copy(): 53 seconds

On a Linux box (same HTML):

====
4.12.3
git checkout 7fb51753743644e23dfb3e7a964d387583dd0bc0
parse HTML, create soup: 22 seconds
copy.copy(): 51 seconds

4.13 - before fix
git checkout 5104c454e47242dfa68e9c6c3b7659e054230017
parse HTML, create soup: 28 seconds
copy.copy(): 55 seconds

4.13 - after fix
git checkout 55c2e34525380ffd83867818169968826a625609
parse HTML, create soup: 28 seconds
copy.copy(): 24 seconds

Great results!! Please feel free to close this as fixed.
