> I can't speak for all of these, but I've noticed over time when viewing stats
> through traffic_top the "DNS lookup" stat will happily persist through a
> restart but at the very least "DNS hits" and the "DNS Hit" percentage will
> not.
> I'm not really sure what the scoop with "DNS Time" is...for me it's always
> 0.0.
> Please let me know if there's any testing I can do to help out, I'd offer up
> a patch but C++ just isn't my cup of tea.
