I did not test W3, just as what @Paul Gibbs said:

I would not recommend W3TC. There is a specific bug with its Object Caching implementation that breaks password resets on BuddyPress for some obscure reason we weren’t able to track down.

You need an Object Cache plugin, which will be backed by a Memcached or Redis instance, or something.

I spend almost more that 3 months to setup cache for buddypress, and finally I agree that Redis object cache is really great for buddypress, including Woocommerce, and actually, I think it would be much great and very helpful to us if there is an instruction of caching setup for buddypress under documentation directory at http://www.buddypress.org, since there are still cache rules need to setup.

and I hope Redis cache experts can share their experience buddypress Forum.

For me, I am using HHVM+php5.6+nginx helper, and using object cache with Redis, and no page cache used.

There are two Redis cache:
https://wordpress.org/plugins/redis-cache/
https://wordpress.org/plugins/wp-redis/

after testing, I found the first one:redis-cache will cause 502 error if buddypress actives steams is enable in Musite by now, and hope the author of redis-cache can upgrade it soon.

and the second one of Wp-redis woring fine with buddypress now.

I read a lot article by Very senior wordpress developers do not recommend Page cache, but strongly recommemd Object cache, here is some for your referrance:

Great
This is quite typical application, I know there is no category support by bp default, so it would be much great if “type” work as category, any plan to develop an plugin to do that?
