We run WordPressMU 2.6.1 in a cluster of Solaris servers behind a load balancer. At present, we've got 700+ users and ~470 blogs (~350 active--others are test/abandoned).
I've made a plea for tips running WPMU in cluster behind a load balancer on the WPMU Forums, but haven't gotten any assistance as of yet (we're still hoping :wink:...
Here're our specs:
- Apache httpd 2.2.8
- MySQL 5.0.51a
- PHP 5.2.5
- Configurable Tag Cloud
- Democracy considering a switch to PollDaddy
- TanTanNoodles Simple Spam Filter
- Viper's Video Quicktags
- WordPress Admin Bar - I understand this isn't ready for WP 2.7
We're running 3 custom themes, which use a proprietary plugin to provide configuration values for analytics, ads, etc.
