“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

slide-15
SLIDE 15

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

slide-16
SLIDE 16

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

slide-17
SLIDE 17

Rails is slow

slide-18
SLIDE 18

Ruby is slow

slide-19
SLIDE 19

“The slowest programming language in the world”

Rails is pretty close to the fastest PHP framework.

Ruby might be slow at fibonacci benchmarks

who cares?

slide-33
SLIDE 33

Ruby is fast at real life web benchmarks

that’s what matters!

Ruby for the web is NOT slow

Enterprise

slide-37
SLIDE 37

Enterprise Enterprise needs enterprise software

slide-38
SLIDE 38

Enterprise

“Enterprise software is software intended to solve an enterprise problem (rather than a departmental problem) and often written using an Enterprise Software Architecture.”

slide-39
SLIDE 39

Enterprise

enterprise problem != departmental problem

slide-40
SLIDE 40

Enterprise

an enterprise problem covers problems from many different departments

slide-41
SLIDE 41

Enterprise

many different departments means different needs/challenges

Enterprise

“Due to the cost

  • f building what is often proprietary software,
  • nly large organizations

attempt to build such software that models the entire business enterprise [...]”

Enterprise

“As many business enterprises have similar departments and systems, enterprise software is often available as a suite of programs that have attached development tools to modify the common programs for the specific enterprise.”

cost

reusable merb slices

Merb::Router.prepare do slice(:blog, :path => "blog") slice(:wiki, :path => "wiki") slice(:public_calendar, :path => "calendar") end

cost

model the entire business enterprise build common tools for common use choose

slide-65

adaptability

because needs differ and change

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.
