Expected Performance?

I've recently begun testing HAProxy[1] as a LB for web servers. Now, using httperf[2] I can get about 2k req/s directly from each Apache instance. With a roundrobin load balance between two Apache instances I can only seem to get 1.5k req/s.

Does this seem like common/acceptable degradation?

[1] HAProxy was compiled ala `make REGEX=pcre DEBUG=` and started
using `./haproxy -f haproxy.cfg`.



            pidfile /var/run/haproxy.pid

    listen  http_proxy      :80
            mode tcp
            balance roundrobin
            server web1
            server web2

[2] httperf command used:

httperf --hog --num-conns=1000 --num-calls=10000 --server= --uri=/apache2-default/index.html Received on 2008/01/03 20:40
