sorry i should have been crisper in my language - there is the new AR async queries (which as you correctly said is a totally different thing). And then there is separately fibered support in activerecord, which will allow the use of the async library for co-op concurrency. Yeah I dont expect single path performance gain, what i'm hopeful for is more concurrency for the same memory across a large pool of web workers in a high scale app. Thus saving a bunch of $$$ EDIT: i just saw your other comment, i suppose you're right w.r.t latencies, there may be less benefit to this than i expected for a standard rails app.
