require grape slow down app about goliath HOT 5 CLOSED

ruby-grape/grape#1122

from goliath.

This sounds like a grape-specific issue. Closing, but feel free to reopen if Goliath is at fault.

p.s. also, make sure you run with -e prod to remove code reloading!

It's not a grape-specific issue. It really seems like code reloading issue.

I generated 1000 empty ruby files:

1000.times do |i|
  File.write("./file#{i}.rb", '')
end

And required them all in your application (instead of require 'grape'):

1000.times do |i|
  require_relative "file#{i}"
end

Then I got a described slow down. However, when running with -e prod the difference is really negligible. You can try it yourself.

When you say the difference is negligible, do you mean the difference of running with and without -e prod?

@dj2

Negligible with and without many loaded ruby files when running with -e prod since code reloading feature is not activated.

That said, almost any library with many dependencies will cause slow down when running in development mode. You just measured a wrong thing.
