Willy, Exactly right, but it is a common misunderstanding.
Out of interest, How hard would it be to get a least connection scheduler to take account of cumulated connections? It would/might make it far more useful for HTTP.. Off the top of my head I think least conns in LVS is based on cummulative for 60 seconds (which again causes a lot of confusion).... Just had a quick look here: http://www.austintek.com/LVS/LVS-HOWTO/HOWTO/LVS-HOWTO.ipvsadm.html and to calculate active conns for LC: active connections = ActConn * K + InActConn Where K is between 32 and 50? So probably way more confusing and yet most of our customers prefer the LeastConnection handling for HTTP in LVS rather than HAProxy.... I also slightly think that they just instinctively like the bigger numbers for connection count ;-). http://blog.loadbalancer.org/look-why-cant-you-just-tell-me-how-many-people-are-connected-to-the-load-balancer/ Just thinking the new keepalive functionality will probably effect this as well?
