Interesting but - as usual - benchmarks are a bit twisted: Manticore knows how to optimize its products, and compare to "out of box" ElasticSeach. However, ES is a really complex stack that REQUIRES a lot of tuning to get decent performances... So I guess that a "real life" benchmark, with every product tuned by experts, would be more significant

Manticore is full C++ so it surely is better than a full stack java ES for memory (and maybe performance) on single server... but ES has a proven history of horizontal scaling (throw more servers to scale). And I didn't see any architectured benchmark. Real ES use case are often based on multiple servers, specialized nodes...

So, all in all... I would be interested in more "real life" use cases before making my mine
