With Intel back to back 10G NIC card, I was able to around 28K reply
rate with 1kb file size with Apache server.
But when using haproxy that means with 3 node setup like
* / \*
* / \*
* / \*
* Client Server*
* *connection rate is good but request rate and reply rate are dropping
drastically. All the three machines are 8 core desktop m/c. On the haproxy
site it has been published that haproxy can sustain more than 30K
I am unable to find out the reason to such a poor performance whether
it is issue with host m/c or haproxy.
