Sets an "X-Runtime" response header, indicating the response time of the request, in seconds
You can put it right before the application to see the processing time, or before all the other middlewares to include time for them, too.
# File lib/sinatra/rack_runtime.rb, line 34 def call(env) start_time = Time.now status, headers, body = @app.call(env) request_time = Time.now - start_time if !headers.has_key?(@header_name) headers[@header_name] = "%0.6f" % request_time end [status, headers, body] end
