From the link: "A 3 node Scylla cluster executes 4.6X more OPS than a similar Cassandra cluster. Only a 30 node Cassandra cluster can level the throughput of the Scylla cluster of 1/10th the size. Yet the 1:10 gain is not the end of it. Latency measurement reveals that Scylla has 4X-10X better P99-latency advantage". Disclosure - I'm kinda involved in Scylla ;)
