title: Should round-robin technique lbmethod=byrequests in apache2 be enough for most scenarios?
body: <p>In my system there are different kind of request having different range in terms of memory cost and time cost. </p>
  
  <p>That is, if there are types of requests R1, R2.....R100, the amount of RAM required to process the request and the response time of these request types varies a lot, even by a margin of 10 to 100 times.</p>
  
  <p>Should round-robin be the right method for such scenario or does round-robin will eventually cover up most scenarios in this situation? </p>
  
  <p>If round-robin is not the right choice, then are there more customizing options available on apache?</p>
