Is there any general consensus on the limitations of a true multisite configuration?
I'm thinking about hosting quite a few sites on one shared host. The sites I want to run are mostly going to be low/medium usage which I would suspect would easily run on a single shared unit under normal circumstances. The plan is to use individual databases with a shared codebase running D5. I'm looking to find out what people think/know about the general limitations on numbers of sites, and numbers of modules in this setup.
- Is there a critical mass for memory, performance or some such?
- Is theran optimum way to run backups to ensure minimum risk?
- How should cron best be configured to ease server load?
- Comments on the above suggested setup?
This is all pretty new to me, so I'm just throwing this out there...
