in peach interval, is the relationship between the speed and the amount of site response to grab. Slow response speed, the crawler will gradually reduce the capture, fast response speed, grabbing quantity will rise, and crawl speed of response peak valley value interval of about 20 days, is about 3 weeks. But also you crawl and host load relationship, in the February to April period, a new server, with CDN, Down server. In order not to continue to increase the complexity of the map, I will not go out.

time interval is black, web crawling quantity and the website included quantity relationship. Grab a large quantity, included the number will also increase, grab less, included the number will be reduced accordingly. The peak amount of grab and included peak interval quantity, in about 15 days, is about 2 weeks. How to understand the way to reduce the number of included, because of a large site, no way to avoid all of the pages are the one and only, or have a high value, the search engine always start after the crawl, gradually eliminating useless pages. Because the operation process need to eliminate useless pages than the storage complex, always need some time to deal with. Every day included new, remove the old. When a new page you grab included less, before >
