In order to get a handle on the performance implications of porting Parsoid to PHP, we need to evaluate the different components of Parsoid.
One of these components is the tree builder that converts a string to a HTML document.
In PHP we will use RemexHtml in place of Domino used in Javascript.
Initial experiments in Feb 2018 indicated that the performance is comparable, but those tests were minimalistic and we didn't document them.
This task is to do some of that evaluation a bit more systematically and document the results here.
