How to know the ES configuration details for benchmark testing?

Hello, I'm really interested in the benchmark data here: https://elasticsearch-benchmarks.elastic.co/#
Just curious where could I find more details about the ES configuration and index configuration? Or is there all used the default value, like the default value mentioned in rally track https://github.com/elastic/rally-tracks/tree/master/nyc_taxis ?

Hi Julius
The actual "car" we use is in a private repo, unfortunately. For NYC Taxis is using a 4gheap however. We use 5 primary shards and 1 replica for tests using 3 nodes. All other configuration details are the defaults of the track. Hopefully thats helpful.
Cheers
Dale

Thanks a lot, Dale.
