 * Hello I want to know which are the limitations of sites numbers and the performance.
   
   We are planning to use WordPress Multisite. Anybody has some numbers or knows
   a case study?
 * I read [http://wordpress.org/support/topic/performance-of-wpmu-vs-single-installs?replies=10](http://wordpress.org/support/topic/performance-of-wpmu-vs-single-installs?replies=10)
   that the performance is the same with 1000 separated blogs and 1000 sites in 
   multisite. Then [http://codex.wordpress.org/High_Traffic_Tips_For_WordPress](http://codex.wordpress.org/High_Traffic_Tips_For_WordPress)
   applies? Only one database to manage 10000 tables is not the same to have 1000
   databases with 10 tables, isn’t it?
 * The last version of wordpress has improvements in switch_to_blog function ([http://codex.wordpress.org/Function_Reference/switch_to_blog](http://codex.wordpress.org/Function_Reference/switch_to_blog))
 * Thanks!
    Antoni

 * I am curious myself. We are a university that has used WP subdomain for 1 year
   now. This is our setup:
    3 dual cpu servers running Apache/WP 1 dual (maybe quad)
   cpu server running mysql 5.1 (myisam)
 * 130 blog sites, adding about 10 sites per month
    1300 tables in database 2 million
   + hits/month (old stats) = medium traffic
 * Running with SuperCache. So far so good =)

 * This is correct.

   > with 10 tables, isn’t it?
 * No, it’s not the same. At that many tables, I’d be looking into SharDB to split
   my DB up a little.
