Will it repeat prefetching URLs

I am suspecting something similar. If quicklink is doing requests for every page separately that would be a bit heavy on the cpu. Especially on high visitor sites. For every user there will be lots of page requests at once thus lots of DB requests. Because all of us have a menu on the top I presume with lots of links :)

In my case I sometimes get max_user_connections error. Maybe caused by this module?

I think we need clarification how this module is actually fetching the pages.

Maybe a maintainer can clear up some info??
