Computing hierarchical score is very slow

[tomas-knap]

I had to commented out the hierarchical score (see 6952fde) as it runs really long - it was executed 20mins+ and did not finish. After commenting it out, it was executed in less then 1 minute (always with empty cache)

@josef-janousek Hi! Is this something you really do work on? If not, remove yourself (if you can), from the assignees. Thx!
