Ruby on Rails' Method Benchmark Performance

Question

I wonder what the benchmark for few rails methods would look like. Anyone got a website that can run custom methods?:

User.count
#=> 1000000 (Let's say about that)

u = User.where(account_id: 5)
u.count
#=> 100000

u.map |a| a.account_id = 6 end

Is there a way to test this sort of benchmark? How slow or fast is that iteration?

What do you try to achieve? There are faster ways in Rails to get the same results. — spickermann, Nov 26 '15 at 11:29

You can use ruby benchmark module for this kind of test

require 'benchmark'
Benchmark.bm do |x|
  x.report { User.count }
  x.report { u = User.where(account_id: 5); u.count }
  x.report { u = User.where(account_id: 5); u.map |a| a.account_id = 6 end }
end
