Simple Ruby Profiler

Simpler than you're lazy

---

What it does?

It helps you find why your Ruby application is terrible slow.

Wow. Audacious. How do I use it?

sp = SimpleProfiler.new
sp.start
slow_method(tons, of, parameters)
sp.stop
puts("report=#{sp.report}")

report={:steps=>[{:caller=>"/your_ruby_file.rb:5:in simple_test", :time=>3.141516}]}

Do you have more examples?

Look that from other example:

WOW. How do I get it?

Copy into your project. Require it (if necessary). Use it.

Q&A

• Wow only one file? - Yep.
• No Gems? - Soon.
• Does it have tests? - Not yet. There is a button for Pull Requests up there. Feel free to press it.
• Do you will make tests for it? - Yes. Soon.
• But already exists tons of better tools in the marked. Why bother doing one more? - You already waste more time reading that than you would need to use it. Also I want to learn Ruby.

• Do I/they need to pay you something? - No.
• Can I change it? - Yep.
• Do I need to put your name on it? - No.
• Do I need to tell someone I'm using it? - Would be nice to make a PR and ask for reviews before put it into production.

• Can I say it if I improve this? - You can say you make it better. Feel free to share with me if you want to.
