I have trouble with HAproxy.
using HAproxy for load balance and backend have 3 squid proxy. But the time
to load a web page with haproxy in front of squid is much more slower than
using squid directly.
this is my conf
global
chroot /loadbalance/haproxy
log 127.0.0.1 local0
maxconn 9000

and more problem is that HAproxy alway use more cpu than expect: ~50% in

I dont know how I can tune the system up?
