I've setup NFA to show the top 100 hosts for increased accuracy.
However when I select "resolve DNS" it can take several minutes for DNS lookups to timeout for un-resolvable Internet IP's (up to a minute).
In these instances I select Top 10 & it displays the page much faster. However, when I select another page, it defaults back to Top 100 again.
I'd like to see the "display top n" as a sticky function. Keep the "top N" setting for all pages & reports unless I change it manually. Sometimes you don't need the details provided by the top 100.
