Yes, but only in front of real applications, in order to stress those
applications before putting them in production.

I'm not familiar with SPECweb2005 configuration. Do you have any pointer
to a diagram ?

>From what I understand, you have a client ("primary client", PC) and a server
("backend simulator", BS), and the SUT sits in between, just like we normally
bench a proxy, except that here, your SUT consists in one machine running
haproxy and a handful of similar web servers to measure. Am I right ?
How do you expect the PC to choose the web server in this test ? haproxy can
do roundrobin, or several other algorithms, and can as well select based on
layer 7 criteria. Also, how do you want the traffic to flow back from the BS
to the PC ? I assume that the BS is just a server which replies to the web
servers, which in turn reply to haproxy which replies to the PC, but all that
is pure guess.
