As Aroop states there can be multiple explanations. One of them is the change to how DocValues are handled in 8.0.0. The indexing impact should be tiny, but mistakes happen. With that in mind, do you have DocValues enabled for a lot of your fields? Performance issues like this one are notoriously hard to debug remote. Is it possible for you to share your setup and your test data? - Toke Eskildsen, Royal Danish Library
