[I posted my reploy to the same message in another thread "Re: Problem
with Native deployment of ruby on rails application on glassfi". Here it
is again:]
As you noted the delay is coming from ActiveRecord/DB adapter. So I
tried depot application with jdbcsqlite3 adapter and inserted the same
code in my store#index controller.

glassfish v3:

As you can see its about the same time. So I dont see any delay here.
-vivek.
