I know Vanilla is trying to go modular in design, are there any plans to remove the activity stuff from the core?
The Activity SQL queries are really slow on a very large forum. Someone simply viewing another persons profile page can take up to 30-60s due to not having indexes and querying a huge amount of data in the activity table. The activity table alone is nearly as large as the discussions table.
Being able to simply disable activity functionality, which is not something I really want in a forum product, would hugely boost vanillas performance for large sites.
