First glance at their github, it looks like they re-implemented Cassandra in C++. 90% components in Cassandra are in scylladb, i.e. compaction, repair, CQL, gossip, SStable.
With C++, I believe this helps performance to some extent up to a point when compaction has not run yet. Then, it will be disk IO to be the dominant factor in the performance measurement as the more traffics to a node the more degrading the performance is across the cluster. Also, they only support Thrift protocol so it won't work with Java Driver with the new asynchronous protocol. I doubt their tests are truly a fair one.
