Current version is 2.1.11
, released 12 June.
i've just migrated a messageboard to vanilla with about 480,000 comments in about 27,500 discussions. so far it's running like a top. i'm wondering if anyone else has done something of this scale yet (maybe with the phpBB importer?) and, if so, if you've noticed any issues with vanilla scaling?
