These graphs are meaningless in a vacuum, you don't know how would behave alternative Go based solution on similar hardware under the similar load.

Sure, this is why there is a production system surrounding them. I am not really interested in theoretical possibilities just observing reality here.

What I am saying is that you are observing one side of reality. It is very possible that even with this kind of graphs, Cassandra is capable to handle much larger traffic then custom Go solution.

Cassandra is usually competitive in open benchmarks.
