Don't know how to build task 'perf:require_bench'

[schneems]

What does the contents of your perf.rake file look like?

[luiszacheu]

I using Devise and add a line to authenticate.
require 'bundler'
Bundler.setup

require 'derailed_benchmarks'
require 'derailed_benchmarks/tasks'

namespace :perf do
task :rack_load do
require ::File.expand_path('../config/environment', FILE)
DERAILED_APP = QprodeliveryWeb::Application
DerailedBenchmarks.auth.user = -> { User.find_or_create!(email: "[email protected]) }
end
end

What do you get when you run

$ rack -f perf.rake -T

[luiszacheu]

Well this command don't work for me, but the command below works:
rake -f perf.rake -T
And get this:
rake perf:allocated_objects # outputs allocated object diff after app is called TEST_COUNT times
rake perf:gc # outputs GC::Profiler.report data while app is called TEST_COUNT times
rake perf:ips # iterations per second
rake perf:mem # show memory usage caused by invoking require per gem
rake perf:objects # profiles ruby allocation
rake perf:ram_over_time # outputs ram usage over time
rake perf:stackprof # stackprof
rake perf:test # hits the url TEST_COUNT times

I using Ruby 2.2.4 and Rails 4.2.5!

That was a typo, i meant rake

It doesn't look like you have perf:require_bench.

Also we don't list that as a command you can run https://github.com/schneems/derailed_benchmarks#running-derailed-exec

I think you want perf:mem or bundle:mem

[luiszacheu]

If i use perf:men works, but this command of Memory used at Require time how a know the total memory my application?

[luiszacheu]

Schneems works now, i remove the redirect if my application had to another page with Devise.
Please can you explain me, how difference when return:
TOP: 155.8789 MiB
application: 73.2578 MiB
activeadmin: 22.6484 MiB
active_admin: 22.6406 MiB
ransack: 15.7891 MiB
.....

The TOP is all memory that my application usage? Or the real value is application?

Thank you!

[schneems]

Top is everything.
