11. “It’s also worth mentioning that
there shouldn’t be doubt in
anybody’s mind at this point that
Ruby itself is slow. It’s great that
people are hard at work on faster
implementations of the language,
but right now, it’s tough.”
Alex Payne, Twitter

12. I for one am scared of Ruby
because ... it's known to be
slow, so if you become The Next
MySpace, you'll be buying 5
times as many boxes as the .NET
guy down the hall.
Joel Spolsky

13. Rails is for the vast majority of
web applications Fast Enough... I
just happen to care much more
about free developer cycles and
am willing to trade the former for
the latter.
David Heinemeier
Hansson

14. Ruby is so embarrassing.

15. Rails is slow

pretty close to
the fastest PHP framework.

30. what about merb?

31. hello world benchmarks
baseline results

32. Merb
merb requests per second

33. Merb Static HTML
requests per second

34. Merb Static HTML PHP

36. We don’t need to be embarrassed

37. Ruby might be slow at
fibonacci benchmarks
who cares?

38. Ruby is fast at
real life web benchmarks
that’s what matters!

39. stop saying Ruby is slow
because that’s not true

41. what about merb?
because that’s why you’re here

42. merb is fast

43. merb is flexible

45. $ merb-gen very_flat app-name
1 file
Merb::Router.prepare do
match('/').to(:controller => 'very-flat-app', :action =>'index')
end
class VeryFlatApp < Merb::Controller
def index
quot;Hi, I am 'very flat' Merb application. I have everything in one single file
and well suited for dynamic stub pages.quot;
end
end

46. $ merb-gen flat app-name
4 files
application.rb - controllers & actions
config/framework.rb - framework config
config/init.rb - app settings
views/view_name.html.erb - action view

47. $ merb-gen core app-name
same as merb stack app
no dependencies
when you don’t want DM
when you use JRuby
when you want an opt-in solution

50. merb can be opinionated

51. merb recycling

52. merb has an api

53. Merb has a bright future for the
people who are not satisfied by the
fixed ways in Rails.
I think that Merb will give users
more freedom in a Ruby-ish
way of programming.
