we've Apache running as reverse proxy using proxy balancer we operate a jMeter load test from 7 Cloud machines however the traffic doesn't appear to obtain distributed evenly I am thinking this is an Apache config problem, although not sure what

essentially within our VirtualHost directive I've:

   ProxyPreserveHost on
   ProxyRequests Off
   ProxyPass / balancer://my-site/
   ProxyPassReverse / balancer://my-site/
   Header add Set-Cookie "route=.%{BALANCER_WORKER_ROUTE}e; path=/"


<Proxy balancer://my-site>
   BalancerMember https://MYMACHINE:8443 route=1 loadfactor=20
   BalancerMember https://MYMACHINE:8443 route=2 loadfactor=20
   ProxySet stickysession=route

in the beginning it didn't have loadfactor=20 and load balancing wasn't done well once i added it there is improvement, although not great, traffic would get routed to at least one-2 machines more then your others (there exists a total of 5 machines)

Note: I have published this to server fault: http://serverfault.com/questions/352066/apache-running-as-reverse-proxy-using-proxy-balancer-traffic-does-not-seem-to-ge

This really is drive insane, any help please? tks
