Spark Memory Management Part 2 – Push It to the Limits In Spark Memory Management Part 1 – Push it to the Limits, I mentioned that memory plays a crucial role in Big Data applications. This article analyses a few popular memory contentions and describes how Apache Spark handles them.
Spark Memory Management Part 1 – Push It to the Limits One of Spark's selling points is that it takes 10-100x less time to finish a similar job written as Hadoop Map-Reduce.

Everyone knows that Linux is faster for software development but I wanted to measure how fast it really is in order to choose the best configuration for myself. That is why, I did several performance tests and this article aims to describe them.
