Will launch N concurrent connections, make a request, and measure how much time took to:

• Open the connection
• Receive the response

Sample run

$ mix excalit --url http://localhost:8080/ --concurrent 2

• The operations are measured in microseconds.
• The "open: xxx us" line indicates how much it took to establish the tcp connection.
• The "recv: .." line indicates (separated by |):
• HTTP status code.
• Body length.
• Time it took to receive the data.

Defaults

• GET method.
• HTTP 1.0.
• 1 connection.
• 0 milliseconds of delay when spawning childs.

Options

• --http11: HTTP version.
• --method get|post|put|delete|head|options|connect: HTTP method to use.
• --concurrent n: Number of concurrent connections.
• --delay n: Delay in milliseconds between each child spawn.
