Re: [Wget-dev] wget2 | Quickly fill DNS cache in background using an external resolver lib (#390)

I was going to make some graphics but as I've seen they are not very useful as 
the data I got (from modifying the PoC) talks by itself. However, here is an 
example (with MAXTRIES set to 3 and MAXWAITING values between 60 and 960, both 
included):

I can send more if someone is interested, but otherwise I don't. I attached 
also the CSV data I got from the PoC so you can take a look. I've calculated 
some averages (with R, which makes easy to load/process all the data) and also 
looked at the CSV-file and I think we should set MAXTRIES to 2-3 (maybe 4 too) 
and TIMEOUT to 2000 or 3000. For MAXWAITING a lot of values look fine (maybe 
600). In every test the resolved number of DNS requests was about 83100-83300 
out of 100000.[file.csv](/uploads/83bbb8752e7118bed12f809a6679ea61/file.csv)
