There is the wish to highlight changes in moved text chunks, which can be realized through changes to the diff engines. The wikidiff2 diff engine needs to be highly performant to cater to the needs of the mediawiki projects. Thus, this ticket aims at bringing both goals together.
Benchmark the performance of the Wikidiff2 diff engine with the changes introduced through T146781: Show changes in moved text chunks (C++) against the performance without the changes.
This is part of fulfilling wish #2 of the 2015 German-speaking community wishlist survey: T139603: Show text changes when moving text chunks (#2)
