It is way more fun to start distributed. Edit the provided config/config.exs with whatever node name suits your fancy. This is optional, and you can stick to the provided one.
config :blitz, master_node: :"[email protected]"
config :blitz, slave_nodes: [:"[email protected]",
:"[email protected]",
:"[email protected]"] Here, the master node is :[email protected]; the rest are slave nodes.
Start up a couple of nodes, and name them accordingly. For example, here's how to start one of them:
% iex --name [email protected] -S mix
Now, when you run the the command
% ./blitzy -n 100 http://www.bieberfever.com
the requests will be split across the number of nodes you created, including the master node. Here's an example run:
