I'd say the benchmark would be complete only when at the point of inflexion the necessary system benchmarks are provided.
Looking at scylladb report it is unclear as to what system parameter was being the bottleneck. Also an observation - its mentioned in the report that they are using 1KB ro and probably using default compression settings so this could be a possible bottleneck (everytime 64K object would be picked off and decompressed even though record is 1/64th the size): https://groups.google.com/forum/#!topic/nosql-databases/9pett319cgs This would really cripple performance if its the case. Tuning 99%ile would be tricky in case of java because of background GC happening - that really has to do with how GC parameters are tuned for the specific workload. I believe its pertinent to evaluate cassandra defaults - 100 MB per core new heap which is recommended the Compression size which can cause troubles.
