John

Can I go?

Usage

$ bundle exec foreman start

Open a web browser: http://localhost:9393

Testing

In a terminal window:

# redis-server

In a separate terminal:

# rake

CLI

$ thor bathroom:status
> The john is not occupied.

Running with init.d

You may need to use sudo for these commands:

$ cp scripts/john.init.d.sample /etc/init.d/john
$ chmod +x /etc/init.d/john
$ /etc/init.d/john start

Load testing

We use JMeter to test server performance.

$ brew install jmeter

# Testing on production
$ RACK_ENV=production rake performance:test

# Testing locally
$ rake performance:test

Then wait. You will see output like:

summary +      9 in    35s =    0.3/s Avg: 14273 Min: 14174 Max:
14397 Err:     0 (0.00%)
summary =     21 in    70s =    0.3/s Avg: 15163 Min: 13002 Max: 20387
Err:     0 (0.00%)

The key metric is the 0.3/s metric, which means that at the 35 second mark, the server was able to respond to 0.3 requests per second.
