## How it works

In my case, the speed of [spider](https://github.com/Tjatse/spider2) is about **1500k documents per day**, and the maximize crawling speed is **1.2k /minute**, **avg 1k /minute**, the memory cost are about **200 MB** on each spider kernel, and the accuracy is about 90%, the rest 10% can be fixed by customizing [Score Rules](https://github.com/Tjatse/node-readability/wiki/Handbook#score_rule) or [Selectors](https://github.com/Tjatse/node-readability/wiki/Handbook#selectors). it's better than any other readability modules.
