Re: Performance issues after Buddypress install
CDN = Content Delivery Network. A place where you upload static files like CSS JavaScript images and anything elses a page would request. This will allow fewer http requests to your server and CDNs make copies of files across globe so clients accessing file will get it fast as it’s closer.
Amazon has S3 CDN or you could simply use DropBox. Other options are header caching for longer periods forcing browser to download copies and keeping them locally.
Most of the WordPress cache plugins work with BuddyPress but youhave to pay attention to the dynamic nature of activity streams / forum posts. You can cache these areas but it should only be for like 30 seconds. But that’s only necessary for sites with thousands if users.
