How to profiling a slow action in Rails?

I have an action costs about 10s:

Completed 200 OK in 9489ms (Views: 1.3ms | ActiveRecord: 71.6ms)

I tried to wrap the whole action with benchmark:

def action
  self.class.benchmark("Processing projects") do
    blahblahblah...
    ...
    ...
  end
end

But it's report looks strange:

how long does it take (692.2ms)
Completed 200 OK in 9489ms (Views: 1.3ms | ActiveRecord: 71.6ms)

I guess that the hidden 8.8s is in certain before_filter or something. But how could I find it? Is it possible to profile an action call at once?
