Now i run a little network of forums in a forum hosting service like Proboards. Soon i want to transfer them in a indipendent website with Xenforo and the Multisite System (i have now 6 xenforo licenses, and soon i will buy 3 others). I have chosed now a VPS, but in the next month i will migrate all on a dedicated server. I need suggestions on configuration, i have read that many users suggest to use Centmin. There are other software/tips that i have to install for optimize my server and lower che cpu/ram usage? As you can imagine, with many forums i will have many nodes (probably 300/400 forums). Do you think can be a problem?
