Explanation / Answer
Answer:-
It is better to divider hosts) rather than separate URLs) between the nodes of a dispersed crawl system, as the host address usually has direct correspondence with the physical location of a host while the URLs may have nothing to do with it.
By looking at the URLs we cannot say where the consistent physical machine (bunch) is located, because of many reasons.
1. There are many international domains which are in use through the world, i.e. g o o g l e .com, g o o g l e .net
2. Many countries top most domain registries allow its users to sell the domains to the residents of third countries. For example, it is possible to buy a domain in US zone g o o g l e .us while being an UK resident and not planning to use it for mostly US users and keep in USA.
3. Also, even if purchasing a domain in your national zone to host a website for the local public, it is sometimes better to keep a server abroad for the sake of savings, security and/or other reasons.
Thus, if URL's are distributed by certain URLs, all the nodes will be up swarming the servers all over the earth that will lead to reduced performance, which is exactly conflicting in host partition.
So, It is better to partition hosts rather than Individual URL's.
