acts_as_taggable_on: how to optimize the query?

Question

I use acts_as_taggable_on in my current Rails project. On one overview page i am displaying an index of objects with their associated tags. I use the following code

Answer 1

I agree with Jan Drewniak, huge performance boosted with

Download.includes(:tags).all

and in views:

download.tags.map {|t| link_to t, t.name}.join(', ')

But still too slow.

Any other idea?
