Processing command: 'repair metadata search of type mods' in 2019.06 only needs 4 minutes for 5.000 documents. Using 2020.06 with ~3.000 documents needs 36 minutes for the same command.

I think we are loosing the time here:
That doesn't look like much, but in sum it is clearly noticeable. My calculation said, that we need 0,72 sec for repairing one document (was 0,048 in 2019.06). Repairing 120.000 documents need now one day (was ~2 hours before).

After some profiling MCREntityResolver seems to use most of the time, see screenshot attached. Changes in this class where made in MCR-2130.
The slow repair is caused by the static content generator: see ifs_handler_*.png screenshot.
