Gabriel, I see the last attachment still only has 2 ES nodes and they really need to bump to 3. Also, I suggested setting limit/request to the same value. We should also shard the larger indices to ensure the load is being spread more evenly.
Making sure you saw my response
@Gabriel, Is there more to be addressed here?
Closing for the time being based on #c25. Please open a new issue with relevant details if needed.
