Ok I recently had to do a lot of optimisation work on MySQL and I found
a lot of contradicting opinions on what to do etc etc etc, then I came
across this page:


on it there is a script someone wrote, he made claims about maintaining
7000 linux servers running MySQL, and the outputted hints from the
script helped me no end.


Since following the advice/suggestions of the script I've stopped
allocating too much or too little ram for MySQL.

NSD is used in combination as some of the root name servers (H, K and L)
these are anycast servers and all the servers for that root run the same
software afaik.

All other root servers run BIND.


So I think it is very much used ;)
