Description

There's been a significant drop in indexing throughput between 2021-04-12 and 2021-05-24 on the NYC Taxis benchmark. Unfortunately several suspects have been merged during that period of time so we might need to git bisect to figure out which one is responsible for the regression. Interestingly the sorted index looks less affected than the non-sorted indexes.
