how does this compare to other multisite deployments
it's constantly growing ( adding about a 1000 sites a year & its only 2 years old )
Also is this many tables what a you would consider "a lot". What concerns should I have and what should I be on the lookout for?
We are planning on upgrading to 3.5.2 from 3.3.1 and I am looking for any plugins or tips that would help improve performance, security, maintenance and management.
Also any pointers on how to upgrade smoothly without affecting too many users would be appreciated.
