Hello, I am setting up a new haproxy server and am getting unusually slow performance compared to a single server solution.

My setup is a 6 server setup. 2 ha proxy front ends, 2 apache web servers, 2 database servers.The servers are all VM servers. There is a 1GB connection between all of them.

When I run a ad test, I am running a straight comparison of

ab -n 250 -c 10 -s 80 http://$sitename

Below are my results.
