We are in the process of creating a system using DNN which has to support thousands of sites and users worldwide in future.

We are unsure of the hardware requirements required to support this case. There is not much hep available on dnnsoftware.com or google which tells us about the ideal DNN hardware requirements.

We have already setup DNN in our local development environment with the following configuration

Farm LoadBalancer

ONE Intel i7 2.6GHz, 8GB RAM, Windows 7 x64 machine with IIS7

Farm Servers

TWO Intel i7 3.4GHz, 8GB RAM, Windows Server 2008 R2 with IIS7

Database Server

ONE Intel i7 2.8 Ghz, 8GB RAM, Windows Server 2008 R2 with SQL Server 2008 R2

This setup is not giving us the performance that we expect out of our system. So we cant just replicate the same environment in production.

Any help related to the hardware requirements will help.
