## Turbolinks test

Well, by now, you've done all your arguing on Twitter. Is Turbolinks a good
idea, or the Worst Thing Ever?

### optimizing a bit early

![don knuth](http://upload.wikimedia.org/wikipedia/commons/4/4f/KnuthAtOpenContentAlliance.jpg) ![tony hoare](http://upload.wikimedia.org/wikipedia/commons/thumb/2/2c/Sir_Tony_Hoare_IMG_5125.jpg/600px-Sir_Tony_Hoare_IMG_5125.jpg)

See these guys? One of them said this:

> "We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil"

Wisdom.

But what makes optimization premature? When you don't know if you should do it
or not. How do you know?

### measure twice, cut once

![measure twice](http://barnraisersllc.com/wp-content/uploads/2010/08/Measuring-Tapes1.jpg)

Measuring. It's good for you. You can do it. If you measure things, you can be
sure what's up.

But like eating your veggies, nobody measures. Ever.

### you're a scientist, dammit

Computer **SCIENCE** is called science for a reason, yo. Be a scientist. Don't
just argue about stuff on blogs. Measure things. Then report back.

### this test sucks

This probably isn't even a good test. I don't care. Tell me how it sucks. Let's
figure it out. But having actual measurements beats complaining about shit on 
Twitter any day.

### what's it do?

Well, it fires up Selenium, and clicks some links. 1000 of them, by default.
Then it prints out how long that took.

## Branches

* [master](https://github.com/steveklabnik/turbolinks_test/tree/master): a plain Rails app.
* [Just CSS](https://github.com/steveklabnik/turbolinks_test/tree/just_css): This has Basecamp Next's CSS file in it.
* [Just JS](https://github.com/steveklabnik/turbolinks_test/tree/just_js): This has Basecamp Next's JS file in it.
* [All the Assets](https://github.com/steveklabnik/turbolinks_test/tree/all_the_assets): This has both.
* [With Little Sleep](https://github.com/steveklabnik/turbolinks_test/tree/with_little_sleep): With a `sleep 0.1` in the controller, to simulate database access
* [With Lots of Sleep](https://github.com/steveklabnik/turbolinks_test/tree/with_lots_of_sleep): Ditto, but `sleep 0.5`.

I've added [some commits to master](https://github.com/steveklabnik/turbolinks_test/commits/master) since I originally forked the branches. If you try this, you
may want to add some of them in.

## To run it:

```
$ bundle
$ rake assets:precompile
$ TIMES=100 rspec
```

Done.

What I get:

With 1000 pages:

```
$ rspec
       user     system      total        real
 no turbolinks 11.170000   0.980000  12.460000 (138.656728)
yes turbolinks 10.800000   0.870000  11.670000 ( 80.436286)
```

With 100 pages:

```
$ rspec
       user     system      total        real
 no turbolinks  1.640000   0.190000   2.140000 ( 15.652763)
yes turbolinks  1.120000   0.090000   1.210000 (  7.776116)
