“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

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

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

Ruby is so embarrassing.

Rails is slow

Ruby is slow

“The slowest programming language in the world”

What does the community say?

Hardware cost

> Development cost

¡we program faster!

¿srly?

benchmarks someone?

Rails with 1 mongrel is

pretty close to the fastest PHP framework.

what about merb?

We don’t need to be embarrassed

Ruby might be slow at fibonacci benchmarks

who cares?

Ruby is fast at real life web benchmarks

that’s what matters!

stop saying Ruby is slowbecause that’s not true

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

merb is fast

merb is flexible

$ 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 "Hi, I am 'very flat' Merb application. I have everything in one single file and well suited for dynamic stub pages." endend

$ 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

$ merb-gen core app-name

no dependenciessame as merb stack app

when you don’t want DMwhen you use JRuby

when you want an opt-in solution

merb is modular

merb is agnostic

merb can be opinionated

merb ♥ recycling

merb has an api

matz likes merb

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.
