Re: WordPress access to bbPress Functions
You should always evaluate the “need” to run WP with BB at the same time. I don’t mean shared login and common cookies which is simple integration, but instead having bbpress load all of wordpress for every page page. That’s a HUGE number of files and mysql calls being generated for every page, multiplied by the number of plugins you have with their own mysql stored settings.
Many times there are ways around loading both at the same time with a few tricks and plugins. If you are on a shared/vps host that’s giving you limited resources you may find streamlining absolutely necessary to deal with any bursts in traffic.
