How it works
In my case, the speed of spider 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 or Selectors. it's better than any other readability modules.
