I am going to design a community site based on buddypress/multisite. I have worked with buddypress/multisite, but never with such a large userbase. There may be 500 users online working actively with buddypress (main site) / their own subsites. My question is:
• What kind of setup (hosting, server) do you recommend for fast and
reliable buddypress/multisite? Can 1 server handle such a load without
• What about plugins? I guess at least Multi-DB plugin is obvious
here. What about easy backup solution for Multi-DB?
• Do you recommend caching for speed in this case? Which cache plugins work well with this
kind of setup?
