'''Links Per Page''' sets how many links each made-up page carries to other pages of the synthetic web. The choices run from 2 to 100.

For a grid it is also the number of dimensions the grid has, so a grid page links to one neighbor along each axis. For a tree it is the number of children each page has. For a power law web it is the number of links each page sends out, however they are spread.

More links per page means a crawl finds new pages faster and the queue server has more to schedule; fewer means a slower, deeper crawl. While a crawl is running this setting cannot be changed, since the pages already crawled were built from it.
