title: Spring cloud performance tunning
body: <p>I'm doing a performance test against a Spring Cloud application. When number of concurrent users exceeds 150, it starts to give "Forwarding error"</p>
  
  <pre><code>{"timestamp":1458685370986,"status":500,"error":"Internal Server Error","exception":"com.netflix.zuul.exception.ZuulException","message":"Forwarding error"}
  </code></pre>
  
  <p>Which parameter I should adjust to get rid of the error? </p>
