I would welcome sharing of information regarding the 'top-tier' PN sites. This should exclude PN specific (self-promotion) sites with the possible exception of postnuke.com where the traffic and performance might be relevant.
What is needed is:-
1) What are the top 10 independent sites using PN rated by numbers of dialy page impressions and numbers of subcribers/members.
2) What is the configuration of these sites (1 or more servers, load balancing, dedicated db server, memory, disks, proxying, bandwidth).
3) What are the collective experiences of developers in terms of Apache/MySQL/PHP max-out levels for given hardware configurations.
Anybody interested in contributing information?
