haproxy in front of Glassfish

[Alexandre MAÏS]

Hello,

I am facing some issues configuring haproxy in front of Glassfish.
 
Today, I have an Apache server with the Glassfish load-balancer plugin 
redirecting to 4 instances of Glassfish. I try to replace this Apache server 
with haproxy.

I have tried to do a load test on the 2 configurations and the results are very 
surprising !
I obtain around 10 000 requests by second with Apache, and only around 4 500 
requests by second with haproxy…
Something in my configuration must not be good, but I can't find it.

So I hope you can help me on this subject. There is my haproxy.cfg :

   global
       log localhost   local7 info
       chroot /home/haproxy/jail
       maxconn 10000
       uid 1001
       gid 1001
       daemon

   defaults
       mode http
       retries 3
       option redispatch
       maxconn 50000
       timeout connect 5000
       timeout client 10000
       timeout server 10000

   frontend front-web 0.0.0.0:80
       log global
       option httplog
       option  dontlognull
       default_backend glassfish
