Not specific to fetcher2, but how are the pages distributed among
different hosts in fetchlist? Have you configured reasonable setting for
generate.max.per.host in nutch conf?

If you generate too many pages for too few hosts there's no way
fetcher|fetcher2 can fetch them fast unless you make it non polite.
