## General Data Analysis

### What is the effect of the different cache on performance?

You can have very good information on [CPU caches](https://en.wikipedia.org/wiki/CPU_cache) on  [this blog page](http://igoro.com/archive/gallery-of-processor-cache-effects/). 

### What should I know about memory?

There is a **very** good and complete review on computer memories [here](https://people.freebsd.org/~lstewart/articles/cpumemory.pdf). In particular the section 6 is good to know for performance programming.
