I don't respond to ad hominem attacks. Let me clear up a few things. Again, the point of the experiment is not to setup the perfect environment for either VM but to subject both Web servers to fair and equal conditions. Whether it is 1GB RAM, 100Mbps switch ports, stock configurations, etc. It's fair game. Now, I don't know if you have experience in the Web hosting business but perfection is not and never will be the goal. Clients could care less about the back-end or details as long as the response they get at the browser is acceptable. That's what drives our efforts in technology. You keep on repeating the idea that no one needs both Varnish and Nginx in their design. Again, there's benefit in running such configuration. It's practical, effective, and thankfully keeps the business flowing. Here's an example of a successful business, besides us ;), doing it: http://www.heroku.com http://www.heroku.com. If you don't realize the benefits of running Varnish over Nginx or Nginx over Varnish in certain situations, that would be one stubborn opinion. So please, stop my wasting my time. Regards Joe
