I&#x27;ll double check, you are probably right. In any case they are coming from HPC background and squeezing hardware to the limit. Also they don&#x27;t use the JVM they compile a popular data science language to native code (I didn&#x27;t sign an NDA but not sure if they want more info to be revealed yet)<p>Running native vs JVM, using hardware capabilities and utilizing every piece of performance they can think of (one of the co founders I think was a CPU designer at Intel or something) lets them get to the theoretical limit of linearity. Spark might get there eventually... But it will take time
