I am looking for hosting for a multisite installation of mainly individual blogs and I am curious about the amount of resources I will need to run the site I want to build. Basically, I want to create a network of about 1000 sites using a full boat of wpmu dev plugins: membership, global tags, rss feeds, etc.
Can anyone give me some numbers on ram, cpu, diskspace, etc? I have done a couple smaller multisite installs, one on shared hosting (which sucked) and one a smaller vps, both of which seemed starved for resources; i.e. out of memory errors, crashes, slow sites, etc.
