<WRAP center round box 100%>
  - 27 = Number of all open connections
  - 221901 = Accepted connections
  - 221901 = Handled connections
  - 442577 = Handles requests
</WRAP>

<WRAP center round box 100%>
  * Requests per connection = handles requests / handled connections
  * Requests per connection = 442577/221901 (pass this to bc -l using echo '442577/221901' | bc -l command)
  * Requests per connection = 1.99
