In linux kernel since version 5.2 (release Date: 2019-07-07)  
The weighted random twos choice least-connection scheduling
algorithm picks two random real servers and directs network
connections to the server with the least active connections
normalized by the server weight.

If you want to compile it in kernel, say Y. To compile it as a
module, choose M here. If unsure, say N.
