_rails-nocache / ruby = 0.15x_

`rails` serves campfire's message fragments from Redis (`cached: true`); `rails-nocache` renders them. The emitted tree has no fragment cache, so `rails-nocache` is the lane that compares renderers and `rails` is the lane that says what a deployment costs.

_rails-nocache / ruby = 0.16x_

`rails` serves campfire's message fragments from Redis (`cached: true`); `rails-nocache` renders them. The emitted tree has no fragment cache, so `rails-nocache` is the lane that compares renderers and `rails` is the lane that says what a deployment costs.

## What each lane rendered

A throughput number for a page that is not the same page is not
a comparison. One authenticated GET per lane per endpoint,
before any load:
